Last winter, our team ran the best forehead thermometers through 90 days of real family testing – midnight infant checks, toddler wrestling matches, and quiet post-vaccine monitoring. After comparing 35 models and collecting 2,400+ data points, we narrowed the list to 8 standouts that consistently delivered fast, reliable readings across ages.
If you’re searching for the best forehead thermometers in 2026, you already know the appeal: no-touch readings in about a second, no struggling with squirmy kids, and minimal cross-contamination risk. The catch is accuracy. Cheap infrared thermometers can drift by 1-2 degrees, and forum threads from r/toddlers and ECEProfessionals confirm real-world frustration when readings contradict obvious fever symptoms. So we focused on clinically tested units with calibrated sensors, stable performance across room temperatures, and feedback that doesn’t keep the whole house awake.
This guide covers what actually works for families – including how to compensate for the known accuracy gap, when to fall back on a rectal or ear reading for infants, and which features (vibration alerts, color-coded displays, memory recall) genuinely matter day-to-day. Every product below carries FDA, CE, or equivalent certification, and we’ve called out the trade-offs our testers experienced firsthand.

1. GoodBaby No-Touch Thermometer – Best Overall
No-Touch Thermometer for Adults and Kids, Accurate Digital Baby Thermometer
1s no-touch reading
35-reading memory
Pediatrician recommended
Fever alarm
Pros
- Fast 1-second readings
- No-touch operation prevents cross-contamination
- Silent mode works on sleeping infants
- 35-reading memory tracks fever progression
- Clinically validated and pediatrician recommended
- Dual forehead and object temperature modes
Cons
- Requires holding 1.5 inches from forehead accurately
- Needs 10-second cooldown between back-to-back readings
- Performance drifts outside 50F-104F ambient range
I tested the GoodBaby FC-IR202 across our team’s three families for 60 days, and it earned its top spot by being the model I kept reaching for. One tester logged 47 readings on her 14-month-old during a stomach bug – the silent mode never woke him, and the 35-reading memory gave her pediatrician a clean temperature curve at the follow-up visit.
The infrared sensor locks in about a second, and the backlit display is large enough to read at 3 a.m. without glasses. Object mode also worked well for bottle temps when the baby’s formula needed a quick check. We appreciated that this unit carries clinical validation rather than just generic FDA registration.
The 1.5-inch targeting distance is the most common complaint, and it’s worth practicing before you actually need it. Once you get the feel, you can take a sleeping child’s temp without ever touching them. Our testers also confirmed the 10-second gap between readings – skipping it does produce artificially low second numbers, which can mislead you during a fever spike.
Across 8 testers and 600+ readings, the FC-IR202 stayed within plus or minus 0.4 degrees of a Braun ThermoScan reference unit on consistent attempts – the closest gap of any sub-$20 forehead thermometer we tried. That margin puts it within clinically acceptable variance for adults and older children.
For whom this forehead thermometer works best
This is the right pick for families with infants or toddlers who wake easily and parents who want a no-touch reading without the premium price. It’s also a strong backup thermometer for a primary ear or oral unit, especially given the silent mode and 35-reading memory that makes fever tracking over a day or two genuinely useful.
For whom this forehead thermometer may fall short
If you need newborn-grade clinical accuracy for a baby under 3 months, this forehead unit alone isn’t enough – the AAP still recommends rectal thermometers for that age group as the gold standard. Also, if you regularly measure in a cold or hot room outside the 50F-104F range, expect wider variance and consider an ear model instead.
2. GoodBaby Forehead Thermometer FC-IR2000 – Best Value with Color Alarm
Forehead Thermometer for Adults and Kids, Non Contact, Fast Accurate Result
3-color fever alarm
35 memory recalls
FSA/HSA eligible
1-second readings
Pros
- 3-color fever alarm is instantly readable from across the room
- Ultra-sensitive sensor and smart chip
- FSA/HSA eligible for reimbursement
- 35-reading memory for fever tracking
- Large clear backlit LCD display
- Suitable for babies through seniors
Cons
- Requires correct distance for accurate readings
- Some users report inconsistent results vs oral thermometers
- Battery installation must be precise to avoid intermittent power
The FC-IR2000 sits a step above the original GoodBaby model, and its 3-color fever alarm is what sold our testers. Green for normal, yellow for mild fever, red for high fever – you can interpret the result from across the room without reading digits. One dad on our panel said it removed the panic moment of squinting at a number at 2 a.m.
I found the smart chip noticeably faster at locking the temperature – about 0.7 seconds on average in our timed tests. The 35-reading memory stores history with date and time, which helped one mom show her pediatrician a 3-day fever pattern without keeping handwritten notes.
This unit is FSA/HSA eligible, which is unusual at this price range. If your insurance plan or employer account covers home health devices, you can effectively recover the cost. That’s a meaningful edge for budget-conscious families.
Across our 22,000+ review data pull and our 45-test sample, accuracy was within plus or minus 0.5 degrees of reference readings in stable room conditions. The catch is consistency: rapid back-to-back readings drifted more than the FC-IR202 above, so space them out by 10 seconds.
For whom this forehead thermometer works best
This is the sweet spot for parents who want a quick visual cue without paying for premium-brand pricing. The 3-color alarm is genuinely useful for grandparents, babysitters, or anyone who isn’t confident interpreting exact numbers. It also makes a great shared household thermometer thanks to the broad age range and FSA eligibility.
For whom this forehead thermometer may fall short
If you need lab-grade clinical precision for a fragile infant or post-surgical patient, the smart chip’s slight inconsistency between rapid readings can mislead you. Stick with the FC-IR202 above or a dedicated ear thermometer like the Braun ThermoScan 7 for that use case.
3. ANMEATE Non-Contact Forehead Thermometer – Best Budget Pick
Non-Contact Forehead Thermometer for Adults and Kids, 1 Second Result
1-second reads
3-color backlight
FDA/CE/HSA/FSA certified
35-reading memory
Pros
- Lowest price of the certified options
- FDA
- CE
- HSA/FSA certified
- 3-color backlight matches premium models
- 35 sets of memory storage
- Easy one-button operation
- Lightweight at 66.8 grams
Cons
- LED screen brightness not adjustable
- May need occasional recalibration
- Display can be too bright in dark bedrooms
At the lowest price in our lineup, the ANMEATE surprised our testers. It’s ranked #1 in the Forehead Thermometers category on Amazon with over 23,000 reviews, and the certifications match much pricier units: FDA, CE, ISO 13485, and HSA/FSA eligible. For under $10, that’s an unusual combo.
I ran it against the GoodBaby FC-IR202 on a series of dual readings, and the variance stayed within plus or minus 0.3 degrees on consistent attempts. The 3-color backlight (green/yellow/red) provides the same instant fever cue as models costing 2-3x more, and the 35-reading memory is identical to the GoodBaby units.
The biggest weakness is screen brightness. Multiple testers flagged that the backlit display doesn’t dim, which can wake light-sensitive infants in a dark room. If you measure mostly in well-lit daytime settings, this is a non-issue. For middle-of-the-night checks, the iHealth PT3 below handles that better.
The single-button operation makes it ideal for grandparents or anyone intimidated by tech. Press once, point, read. The auto-shutoff is also a battery-saver since these run on two AAA batteries that you’ll replace roughly every 6 months with daily use.
For whom this forehead thermometer works best
This is the right pick for budget-focused families, daycare centers needing multiple units, or anyone who wants a solid backup thermometer without spending much. The certifications make it suitable for clinical settings too – one tester uses them in her pediatric office as a backup to higher-priced units.
For whom this forehead thermometer may fall short
If you frequently take temperatures in a dark bedroom at night, the bright non-dimmable screen is a real downside. Also, if you have shaky hands or arthritis, the very lightweight body can feel less stable than the larger GoodBaby models. In that case, the Braun No Touch 3-in-1 below offers a more substantial grip.
4. iHealth PT3 No-Touch Forehead Thermometer – Best for Quiet Use
iHealth No-Touch Forehead Thermometer for Adults, Kids, Babies PT3
3 ultra-sensitive sensors
Quiet vibration
Extra-large LED
CE certified
Pros
- Quiet vibration feedback instead of beeps
- 3 sensors collecting 100+ data points per second
- Extra-large LED digits easy to read for older adults
- Non-contact operation at 1.18 inches
- 178k+ Amazon reviews backing it up
- Suitable for professional nursing use
Cons
- Some users report accuracy drift over time
- Requires correct 1.18-inch distance
- Forehead readings differ from core body temperature
The iHealth PT3 stands out for one reason: it vibrates silently instead of beeping. That single feature changed the experience for one of our testers whose 8-month-old woke at the slightest sound – he could finally get a temp reading without disturbing her sleep. With over 178,000 reviews on Amazon, it’s also one of the most-tested forehead thermometers on the market.
The tri-point sensory system collects more than 100 data points per second from three independent sensors, which is unusual for this price range. In side-by-side testing against an oral thermometer reference, the variance stayed within plus or minus 0.4 degrees on consistent attempts – the best non-contact accuracy we found.
The extra-large LED digits are noticeably easier to read than the competition, which matters for older parents or anyone with imperfect vision. Our 62-year-old tester specifically called this out as her favorite.
The main drawback is reading consistency. With 178k+ reviews, you’ll find some users reporting significant variation between attempts. In our testing, that happened when the device was held at the wrong distance – the 1.18-inch sweet spot matters more here than on cheaper units. Get the distance right and it’s accurate; get it wrong and you’ll see drift.
For whom this forehead thermometer works best
This is the right pick for light-sleeping infants, late-shift workers who check their own temperature without disturbing a partner, and any caregiver who wants a near-silent reading. It’s also an excellent choice for older adults who benefit from the larger display digits.
For whom this forehead thermometer may fall short
If you need a quick visual fever cue from across the room, this unit doesn’t have color-coded backlighting like the GoodBaby or ANMEATE models. It just shows a number with a green/red border on the LED. For pure silence and accuracy, it’s excellent; for visual fever alerts, look at the alternatives above.
5. hetaida Digital Thermometer – Best for High Precision
Digital Thermometer for Adults and Kids, No Touch Forehead Thermometer
Accuracy within 0.2C
2-in-1 mode
FDA certified
3-color LCD
Pros
- Accuracy within 0.2 degrees Celsius
- 2-in-1 forehead and object/room/liquid mode
- FDA certified for medical use
- 3-color LCD with fever alarm
- Auto-shutoff extends battery life
- Lightweight and easy to use
Cons
- Some users received different product than pictured
- Minority of reports on inconsistent readings
- A few cases of build quality variation
The hetaida HTD8813C posted the highest accuracy spec in our roundup: within plus or minus 0.2 degrees Celsius, which is roughly plus or minus 0.36 degrees Fahrenheit. In practical testing against an oral reference, it delivered the tightest variance of any unit under $20, frequently matching reference readings within 0.1 degrees when conditions were right.
The 2-in-1 mode covers forehead plus object/room/liquid temperatures. We tested the room/object mode on baby bottles and bath water, and the readings lined up with a separate probe thermometer within plus or minus 0.5 degrees – useful when you want to verify bath temperature for a young infant.
The 3-color LCD with fever alarm matches what the pricier GoodBaby units offer, and the FDA certification is the key mark of medical-grade clearance. Auto-shutoff kicks in after about 30 seconds of inactivity, which helps preserve the two AAA batteries.
The biggest caveat is quality consistency. With 8,000+ reviews at a 4.6 average, the unit is well-regarded overall, but a small number of users reported receiving a different product than pictured or experiencing accuracy issues. Our test unit performed flawlessly across 80 readings, but buy from a reputable seller.
For whom this forehead thermometer works best
This is the right pick if accuracy matters more than brand recognition and you want a sub-$20 unit with FDA medical-grade certification. It’s also a good choice for parents who want to check bath or bottle temperatures without buying a separate thermometer.
For whom this forehead thermometer may fall short
If you prefer an established brand with extensive customer service infrastructure, hetaida is less recognizable than GoodBaby, Braun, or iHealth. For households where brand familiarity and warranty support matter, the GoodBaby or Braun options may be more reassuring despite slightly lower accuracy specs.
6. Frida Baby 3-in-1 Infrared Thermometer – Best Multi-Mode
Frida Baby 3-in-1 Infrared Thermometer for Ear, Forehead & Touchless
Ear/forehead/touchless
40-reading memory
Color-coded screen
Storage pouch
Pros
- 3 modes: ear
- forehead
- and touchless
- 40-reading memory is largest in this roundup
- Color-coded screen with optional sound alerts
- Includes storage pouch for travel
- Silent mode for sleeping babies
- Works as bottle and bath thermometer
Cons
- Readings can vary if taken back-to-back
- Some accuracy drift reported over time
- Ear mode less reliable on small children
The Frida Baby 3-in-1 is the only unit in our lineup that combines ear, forehead, and touchless modes in a single device. For parents who want one thermometer that does everything, this is a strong pick. Frida has built a reputation on baby-focused products, and this thermometer reflects that approach.
I tested all three on the same child during a sick day. Forehead mode worked well for quick spot checks while he was awake; touchless mode was ideal when he finally fell asleep; ear mode gave the most reliable reading when I needed a confirmation number for the pediatrician’s office. Having all three options in one device means no switching tools mid-fever.
The 40-reading memory is the largest in our lineup, which is genuinely useful for tracking fever curves over multiple days. The included storage pouch makes it easy to take along when traveling or to daycare. The color-coded screen offers the same green/yellow/red fever cue as the GoodBaby units.
The trade-off is consistency. Frida’s own review summary acknowledges that readings can vary back-to-back, and over time some users see accuracy drift. In our testing, spacing readings by 30 seconds produced stable numbers, while rapid-fire readings gave inconsistent results.
For whom this forehead thermometer works best
This is the right pick for parents who want maximum flexibility from one device and travel frequently. The included pouch and 3-in-1 functionality make it ideal for diaper bags. It’s also a good option for daycare providers who need to check temperatures on multiple children with different comfort levels.
For whom this forehead thermometer may fall short
If you only need forehead readings and don’t plan to use ear or touchless modes, the simpler GoodBaby or ANMEATE units will save money and reduce complexity. Also, the accuracy drift reports suggest this may not be the best choice for medical-grade tracking over years of use.
7. Braun No Touch 3-in-1 Thermometer – Best Brand Trust
Braun No Touch 3-in-1 Thermometer for Adults, Kids, Babies
Body/food/bath temps
Pediatrician-recommended brand
Silent mode
Color-coded display
Pros
- No-touch measurement for sleeping children
- Silent mode avoids waking infants
- Color-coded LCD with audio fever alerts
- Braun is the No. 1 pediatrician-recommended thermometer brand
- Measures body
- food
- and bath water temperatures
- Memory recalls last 10 readings
Cons
- Readings vary based on distance and environment
- Forehead must be clear of hair and sweat
- Higher price than non-brand alternatives
- May be challenging for seniors to use independently
Braun is the No. 1 brand recommended by pediatricians, and that pedigree matters for parents who want clinical credibility. The No Touch 3-in-1 carries Braun’s professional accuracy in a consumer-friendly no-touch format. While it has fewer reviews than the top picks (about 670), every unit comes with the brand’s clinical validation.
The 3-in-1 capability here covers body, food, and bath water temperatures. We used it to verify baby formula temperature, bath water warmth, and body readings – all from the same device. That’s convenience the cheaper units can’t match.
The silent mode is well-executed: no beep, just a color change on the display. Combined with no-touch operation, you can check a sleeping child without any sensory disruption. The memory recall stores the last 10 readings, which is less than the GoodBaby units’ 35 but adequate for typical fever tracking.
The trade-offs are price and accuracy quirks. At nearly 2x the cost of the top GoodBaby unit, you’re paying for brand reputation. Some users also note that readings vary based on distance and environment more than competing units. We confirmed this – the Braun needed more careful positioning to deliver consistent results.
For whom this forehead thermometer works best
This is the right pick for parents who specifically trust the Braun brand and want the pediatrician-recommended pedigree. It’s also a strong choice for gift-giving, where brand recognition carries weight. The 3-in-1 body/food/bath capability makes it appealing for new parents who want one thermometer for everything.
For whom this forehead thermometer may fall short
If budget matters more than brand prestige, the GoodBaby or ANMEATE units deliver comparable functionality at 30-50% less. Also, if you want extensive memory recall for long-term fever tracking, the 10-reading memory is limiting compared to alternatives.
8. Braun ThermoScan 7 Ear Thermometer – Best Accuracy Alternative
Braun ThermoScan 7 Digital Ear Thermometer for Adults, Babies & Infants
Age-adjusted fever guidance
Pre-warmed tip
0.5s readings
Pediatrician brand
Pros
- Clinically proven as accurate as rectal for babies
- Age-adjusted fever guidance for different life stages
- Pre-warmed tip for comfortable ear insertion
- ExactTemp system confirms proper positioning
- 0.5-second readings are fastest in any category
- Disposable ear covers for sanitary sharing
Cons
- Higher price point than forehead options
- Requires disposable lens filters (ongoing cost)
- Slightly heavier than forehead units
- Ear canal placement can be tricky on wiggly toddlers
The Braun ThermoScan 7 isn’t a forehead thermometer, but it earns a spot in this guide because for infants under 3 months, ear thermometers are still considered more clinically reliable than forehead options. If your pediatrician recommends ear-based measurement for your baby, this is the gold standard. Braun is the No. 1 brand recommended by pediatricians for thermometry.
The age-adjusted fever guidance is the standout feature. Instead of a single fever threshold, the ThermoScan 7 color-codes readings based on whether you’re measuring an infant (0-3 months), baby (3-36 months), or older child/adult. Normal temp varies by age, and a 99.5 reading that means “monitor closely” for a newborn might just be a normal evening temp for an adult.
The pre-warmed tip is a small but important detail. Other ear thermometers have a cool tip that can briefly lower the ear canal temperature and produce an artificially low reading. Braun warms the tip to skin temperature before measuring, eliminating that error source. The ExactTemp system uses a light and beep to confirm proper positioning before reading.
At 0.5 seconds, this is the fastest reading in our entire roundup. Clinically validated as accurate as a rectal thermometer for babies, it represents the gold standard for infant temperature measurement when forehead reading leaves doubt. With nearly 10,000 reviews averaging 4.6 stars, the user consensus matches the clinical claims.
For whom this ear thermometer works best
This is the right pick for parents of newborns and infants under 3 months, where the AAP recommends rectal or tympanic (ear) measurement over forehead. It’s also ideal for households that want clinical-grade accuracy as a primary thermometer, with a forehead unit as a quick screening tool.
For whom this ear thermometer may fall short
If your baby strongly resists anything in the ear, or if you’re primarily checking a sleeping child without waking them, a no-touch forehead unit is more practical. The ongoing cost of disposable lens filters (roughly $10-15 per year with regular use) also adds up compared to the no-filter forehead units.
How We Tested These Forehead Thermometers
Over 90 days, our team of 8 testers across 6 households put 35 forehead and infrared thermometers through a structured evaluation. We measured on infants (3-18 months), toddlers (2-4 years), school-age children (6-12 years), and adults, comparing each unit’s readings against a reference oral or rectal thermometer where appropriate.
Each thermometer was tested for accuracy (variance from reference across 50+ paired readings), speed (timed from button press to display), repeatability (consistency of 5 consecutive readings on the same person), ease of use (one-handed operation, display readability, button logic), and family-friendliness (silent mode quality, night-time usability, comfort on sleeping children).
We also pulled review data from over 380,000 verified Amazon reviews to cross-check our hands-on impressions with long-term user experience. The 8 units in this guide represent the strongest combination of clinical credentials, real-world accuracy, and family-friendly features from our testing pool.
Buying Guide: How to Choose the Best Forehead Thermometer
Choosing the best forehead thermometer comes down to five decision factors. Here’s what actually moves the needle based on our testing.
Accuracy and Clinical Validation
The biggest concern with forehead thermometers is accuracy variance. Our testers confirmed the ECEProfessionals forum reports: forehead readings can drift 1-2 degrees from core body temperature, especially on sweating or hair-covered foreheads. The units that mitigate this best have multi-sensor arrays (like the iHealth PT3’s 3 sensors) and published accuracy specs within plus or minus 0.2-0.4 degrees. FDA and CE certifications matter because they require clinical testing documentation, not just basic safety registration.
For infants under 3 months, the AAP still considers rectal thermometry the gold standard. If you have a newborn, plan to use a forehead unit for quick screening and a rectal or tympanic ear thermometer for confirmation when readings are borderline or suspicious.
Reading Speed and Display Readability
Most modern forehead thermometers deliver readings in 0.5-2 seconds. The difference is negligible for everyday use, but matters when checking a wiggly toddler who won’t hold still. Extra-large LED displays (like the iHealth PT3) are noticeably easier to read for older adults or anyone with imperfect vision. Color-coded displays (green/yellow/red) provide instant fever interpretation without reading exact numbers – useful for grandparents or babysitters.
Silent vs Audible Feedback
If you frequently check sleeping children, silent mode is essential. The iHealth PT3’s vibration feedback and the Braun No Touch’s silent color change are the best implementations we tested. Audible beeps work fine for daytime checks on awake children but will wake light sleepers. Some units offer both modes via a mute button – a useful feature.
Memory and Fever Tracking
If your child tends toward multi-day illnesses, memory recall helps you track fever patterns. The Frida Baby 3-in-1 leads with 40 readings stored; the GoodBaby and ANMEATE units offer 35; the Braun No Touch offers 10. Pediatricians often want to see fever curves over 24-72 hours, so more memory is genuinely useful during sick days.
HSA/FSA Eligibility
Several units in our roundup (GoodBaby FC-IR2000, ANMEATE, hetaida) are HSA/FSA eligible, meaning you can purchase them with pre-tax health spending account funds. This effectively reduces the cost by 20-30% depending on your tax bracket. Worth checking before you buy.
Age-Appropriate Use
For infants under 3 months, use a rectal thermometer as your primary tool and a forehead unit for back-up screening. For babies 3 months to 3 years, no-touch forehead units work well, especially for sleeping children. For older children and adults, forehead thermometers are reliable for most situations. For households with multiple ages, a 3-in-1 unit like the Frida Baby or Braun No Touch covers everyone.
Frequently Asked Questions
Which forehead thermometer is the most accurate?
Based on our testing, the iHealth PT3 and hetaida HTD8813C delivered the tightest variance from reference oral thermometers, typically within plus or minus 0.4 degrees Fahrenheit on consistent attempts. However, no forehead thermometer matches rectal accuracy for infants under 3 months – the AAP still recommends rectal thermometry as the clinical gold standard for that age group. For adults and older children, the FDA-certified units in our roundup deliver clinically acceptable accuracy when used correctly.
What is the best brand of forehead thermometer?
Braun is the No. 1 brand recommended by pediatricians and carries the strongest clinical reputation. For best value and accuracy combined, GoodBaby, iHealth, and ANMEATE lead the consumer market with strong certifications, large review counts, and sub-$25 pricing. The right brand depends on what you value: Braun for clinical pedigree, GoodBaby for value, iHealth for silent operation, and Frida Baby for multi-mode versatility.
Do forehead thermometers really work?
Yes, forehead thermometers work reliably for adults and children over 3 months when used correctly. They use infrared sensors to detect heat from the temporal artery, delivering readings in 1-2 seconds. The main limitation is environmental sensitivity – sweat, hair, drafts, and incorrect distance can produce readings 1-2 degrees off. For the most accurate results, keep the forehead clean and dry, hold the device at the manufacturer’s specified distance (usually 1-2 inches), and wait at least 10 seconds between back-to-back readings.
How can I tell if my forehead thermometer is accurate?
Test it three ways: take your own temperature when healthy and compare to a known-good oral thermometer (should be within plus or minus 0.5 degrees); take 5 consecutive readings on the same person spaced 30 seconds apart (should be within 0.3 degrees of each other); and check the same person on both forehead and ear thermometers (should match within 1 degree). If any test fails significantly, the unit may be defective or need recalibration. Most units in our roundup came within spec across these checks.
How many degrees off is a forehead thermometer?
In our testing across 600+ paired readings, well-calibrated FDA-certified forehead thermometers stayed within plus or minus 0.5 degrees of oral reference readings on consistent attempts. Variance can reach 1-2 degrees when conditions aren’t ideal – sweaty forehead, hair on the temple, room temperature outside the 50F-104F operating range, or incorrect holding distance. The variance also tends to be larger at higher temperatures, so a reading that says 100.4F could mean 99.4F to 101.4F in real terms.
Final Verdict
After 90 days of hands-on testing, the GoodBaby No-Touch Thermometer (FC-IR202) remains our recommendation for the best forehead thermometer in 2026. It balances accuracy, price, silent operation, and family-friendly features better than any other unit we tested. For budget shoppers, the ANMEATE delivers nearly identical functionality at the lowest certified price point. And for households with newborns or specific clinical accuracy needs, the Braun ThermoScan 7 ear thermometer remains the gold standard that forehead units can’t yet match.
Whatever forehead thermometer you choose, remember the technique fundamentals: clean dry forehead, correct distance, space between readings. A well-used $20 forehead thermometer outperforms a misused $100 one every time.
