Clip-On Freezer Thermometers
Monitor temperature in freezers, coolers, and storage areas with these thermometers.
The indicating color changes to red if the temperature gets too high for thermometers with a color changing temperature zone indicator, alerting you to make adjustments. Thermometers with a blinking temperature zone indicator will blink continuously to indicate that too high of a temperature has been reached.
Thermometers with a scale display are filled with mercury-free fluid for a quick response time. Thermometers with a dial or digital display make it easier to see small temperature fluctuations than those with a scale display.
NSF/ANSI 2 thermometers meet standards for food equipment. They show a blue indicating color when the temperature is in the safe zone for food.
Thermometers with a timer measure how long the temperature stays outside the safe zone, which helps you know if products are still viable after a power outage. Their min/max memory records the highest and lowest temperatures. When the temperature is in the safe zone for food, they show a green indicating color.
