Questions about this item

How accurate is the reading when the probe stays in a steady room-temperature environment all day?

The specification lists a room-temperature accuracy of ±2.7 °F (±1.5 °C), so sustained use at stable ambient conditions will stay within that tolerance.

Does the backlit display or continuous operation cause noticeable heat or battery drain during a full work shift?

The unit runs on two LR44 cells and auto-powers off after a period of inactivity; no heat or noise is produced, and battery life is sufficient for extended daily use.

What power source must I have on hand before the thermometer will work out of the box?

It requires two LR44 button-cell batteries, which are not included, so you need to supply them yourself.
