Monitor air temperature levels inside freezers, refrigerators, display cases, water tanks, and coolers with the Min/Max Alarm Digital Thermometer. For a spot check or permanent installation, the Min/Max is an economical and convenient QA tool.

Its onboard internal sensor shows ambient air temperature, while the fast response stainless steel external sensor attached to a 10-ft (3 meter) cord shows the temperature to which it is exposed. Alarms can be set for high and low temperature readings.
