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.

Remote-Reading Magnetic-Back Thermometers with Calibration Certificate


Externally monitor the air temperature inside freezers, refrigerators, water baths, and incubators. These thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They have a probe with a 10-ft. cable that connects to a magnetic-back external display. The probe is insulated in a bottle filled with mercury-free fluid to prevent false readings from rapid temperature changes such as opening freezer doors.
The display simultaneously shows the high, low, and current temperatures. These thermometers have a programmable alarm to indicate when temperature rises above or below your actuation point.

Remote-Reading Panel-Mount Thermometers





Monitor the temperature of difficult-to-access system components from a distance. The probe is connected to a cable, so the dial can be mounted away from your system.
Thermometers that meet NSF/ANSI standards are for use in food processing and preparation areas.
