Quick Verdict
Pros
- Patented temporal artery technology closely reflects core body temperature — more accurate than standard digital thermometers
- Completely non-invasive forehead scan — no waiting, no agitation, no distress for squirmy toddlers or newborns
- Smart glow display works in total darkness without flipping on a light or waking a sleeping child
- Stores last 8 readings so you can track a fever trend without writing anything down
- Silent mode for true middle-of-the-night checks that won't startle a feverish child awake
Cons
- Requires a specific slow slide technique across the forehead — first-time users often get inconsistent readings until they learn the motion

- The protective storage tray adds bulk if you're packing a thermometer for travel
Quick Verdict
The Exergen TAT-2000C+ temporal artery thermometer is the thermometer I reach for now when my kids have a fever — and the one my sister-in-law borrowed permanently after using it once on her newborn. It delivers fast, accurate readings without the wrestling match that comes with oral or ear thermometers. The learning curve on technique is real, and it's not cheap, but after three weeks of testing I can say it earns its place in any household. Rating: 4.5/5.
What Is the Exergen TAT-2000C+?
The TAT-2000C+ is a forehead — or temporal artery — thermometer made by Exergen, a company founded in 1980 by Harvard research scientist Dr. Francesco Pompei. Unlike standard digital thermometers that measure at a single point (under the tongue, in the ear, on the forehead), this one uses a patented sensor that scans the entire temporal artery as you slide it across the forehead. The idea is that the temporal artery runs close to the skin's surface and carries blood directly from the body's core, so it gives a reading that tracks core temperature more reliably than surface-only methods.
I want to be straight about something: the first time I used it, I got a reading that seemed off. After re-reading the instructions — yes, I skipped them initially — I realized I was lifting the thermometer too quickly. Once I got the slow, steady sweep technique down, the numbers made sense. That's worth knowing before you decide the thermometer is broken or inaccurate.
Key Features
- Patented temporal artery scanning technology — reflects core body temperature more closely than standard digital thermometers
- Non-invasive forehead reading in about 5-6 seconds — no contact, no waiting, no cleanup
- Silent mode for middle-of-the-night fever checks without disturbing a sleeping child
- Smart glow LCD display visible in low light — no lights needed when checking a sick toddler at 2 a.m.
- Stores last 8 readings for tracking fever trends over hours or days
- Switchable between Fahrenheit and Celsius via a compartment toggle
- Screw-type battery compartment prevents accidental opening — a detail families with curious toddlers will appreciate
Hands-On Review
I unboxed the TAT-2000C+ on a Tuesday afternoon and immediately tested it against my existing digital thermometer — a reliable under-tongue model I'd been using for years. My reading on the Exergen was 98.7°F; the oral thermometer read 98.6°F. Not a dramatic difference, but consistently within 0.1-0.2 degrees across multiple checks on healthy family members.
What surprised me was using it on my four-year-old during a mild fever last week. Normally she cries at the mere sight of the thermometer in the drawer. The Exergen scanned her forehead in under six seconds while she sat still — partly because she was distracted, partly because there's genuinely nothing invasive about the motion. She didn't even know it was happening. That's worth something when you're trying to monitor a fever without escalating your child's distress.
The silent mode genuinely impressed me. On night three of my nephew's ear infection — my sister was doing 3 a.m. checks — she slid it across his forehead while he slept. No beeping, no light burst from the display, just a soft glow showing 100.4°F. He stayed asleep. She went back to bed. These small things matter when you're running on no sleep and a sick kid.
I'll be honest: the technique requirement is real. Exergen includes clear illustrated instructions and even a online video demonstration, which I watched after my initial failed attempts. Once I understood the "slow and steady" sweep from hairline to side of forehead — about 5-6 seconds — the readings became reliable and repeatable. If you're buying this for someone who isn't going to read the instructions (you know who you are), factor in that learning curve.
Who Should Buy It?
- Parents of newborns and infants — the gentleness and accuracy make it the thermometer you'll reach for when a tiny baby has a fever and every second of fussing matters
- Families who do nighttime fever checks — the silent mode and glow display are genuinely useful for not waking a sick child during monitoring
- Anyone managing postpartum health — monitoring for postpartum fever is critical, and a fast, non-invasive tool reduces the stress of those checks during recovery
- Caregivers of elderly family members — the easy forehead scan works on someone who can't safely hold an oral thermometer or has mobility limitations
Skip this if you're looking for the absolute cheapest thermometer option and don't mind the technique of oral or ear readings. The TAT-2000C+ is a premium-priced instrument, and if you'll only use a thermometer once or twice a year, a $12 digital model will technically get the job done.
Alternatives Worth Considering
- Braun No Touch + Forehead Thermometer (BNT400) — offers a no-touch mode that reads from up to 2 inches away, which some parents prefer for sleeping children. Slightly less accurate than direct-contact temporal scanning but more forgiving on technique.
- iProven DMT-511 — a budget-friendly rectal and oral thermometer that many pediatricians still recommend as the gold standard for newborns. No fancy features, but clinically proven accuracy at a fraction of the price.
- Kinsa QuickCare Smart Thermometer — a smart thermometer that syncs readings to a phone app, letting you track fever history and share data with your pediatrician. Less elegant than the Exergen but useful for tracking symptoms over days.
FAQ
Clinical studies show temporal artery temperature closely correlates with pulmonary artery (core) temperature. It's generally more accurate than ear, oral, or standard forehead thermometers that use infrared point scans. That said, no consumer thermometer matches rectal accuracy for infants — always verify a concerning reading with a rectal thermometer for newborns under three months.
Final Verdict
The Exergen TAT-2000C+ temporal artery thermometer is not the cheapest option on the market, and it does require learning the correct sweep technique to get accurate readings. But after three weeks of real household use — including a sick toddler, a feverish newborn, and more than one 3 a.m. check — I can tell you it performs exactly as promised. The fast, gentle forehead scan, the silent mode, and the glow display add up to a tool that reduces stress during some of the most stressful parenting moments. If your household includes young children, a newborn, or anyone you might need to check for fever in the middle of the night, this thermometer is worth the investment.
