underarm thermometer

Many underarm thermometers are multi-use and support oral, rectal, and underarm measurements, suitable for infants through adults.

Reported accuracy varies by model. Some list clinical accuracy of ±0.2°F (±0.1°C) and precision to 0.1°F (one-tenth of a degree).

Common extras include a protective storage or carrying case, disposable probe covers, and batteries included in the package.

Age guidance varies by model—some are listed for newborns through adults, while at least one listing specifically suggests 0–6 months as a recommended range.

Times vary by model: many list readings around 8 seconds, some advertise a 10-second quick read (with a 30-second double-check), and others specify about 30–40 seconds for underarm use.

Product descriptions commonly highlight a flexible or soft tip—often described as extra-soft—to make underarm (and oral) checks more comfortable.

Displays are typically digital or LCD screens; many models offer large or backlit displays, memory recall, and fever indicators such as color-coded displays, fever bars, or audible alerts.

Battery types vary by model; product details list cells such as LR41 alkaline, CR1220 lithium, CR1632 lithium, and CR2032 lithium.
