Digital Oral Thermometer

This thermometer uses a fast-read sensor tip that settles on a stable reading in roughly 10 seconds for oral use, which matters most with kids or anyone who has a hard time holding still. The tip itself is flexible rather than rigid plastic, so it sits more comfortably under the tongue or in the underarm position without feeling like a hard probe.

The display is backlit, which sounds like a small detail until you're trying to read a thermometer at 2 a.m. without turning on an overhead light. The backlight switches on automatically when the unit powers on and stays lit long enough to read the number comfortably before it times out.

A last-reading memory function stores the previous measurement so you can compare it to the current one without writing anything down — useful for tracking whether a temperature is trending up or down over the course of a day. The unit takes a single replaceable button-cell battery and includes a hard plastic storage case that keeps the tip protected in a drawer or bag.
