Claimed accuracy achieved View more details.

Digital probe models are tested in our lab's accurate thermal bath. For infrared ear/forehead thermometers, our tester takes a range of readings on himself in appropriate conditions with a rest in between, and compares results to an accurate reference digital probe thermometer (used orally at the same time as the tested model). Infrared models should generally be within their claimed range of accuracy (+/-0.2C or +/-0.3C) of an oral reading.
