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.

Clip-On Thermocouple Probes for Air
With a clip on the end, these probes are quick to install and easy to remove. They're often used on vents, circuit boards, and other irregular surfaces. Their tip is exposed, so they respond to rapid changes in air temperature but can’t be used in liquids. The coiled cable stretches when you need extra reach.
Pick the thermocouple type that best covers the temperature range you expect your environment to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. These probes are often used with temperature controllers, thermometers, and other temperature-reading devices.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.
