The Cold Zone Infrared Thermometer is a non-contact infrared thermometer that measures surface temperatures in walk-ins, freezers, and cold storage units with confidence. The Cold Zone Infrared Thermometer is not affected by drastic changes in ambient temperature, and allows you to check cold temperatures all day long without waiting for instrument equilibration.

The Cold Zone Infrared Thermometer is perfect for measuring surface temperatures in grocery stores, food processing, food storage, cold chain monitoring, transportation, restaurants, convenient stores, HVAC, inspection, and general purpose industrial. The Cold Zone Infrared Thermometer outperforms other infrared guns at three times the cost in low-temperature applications.

Emissivity is adjustable on the Cold Zone Infrared Thermometer so you can point and measure just about any surface. Check out our emissivity chart for approximating your material.

Each Cold Zone Infrared Thermometer ships with a certificate of conformance stating that we used our NIST-Traceable equipment to check each one. An optional calibration certificate is available with test data. Also included with the Cold Zone Infrared Thermometer is a convenient neck lanyard and installed battery so it's ready to use right out of the package.

Ambient Effect

The CZ-IR is always ready to measure temperature accurately as you move from warm to cold environments.

This graph displays the error found in most IR thermometers when you take them into a cold environment. The competition requires you to allow up to 30 minutes for the IR thermometer to overcome ambient temperature errors.

No laser directing beam.

The Cold Zone Infrared thermometer works well, but at first I was not pleased. Most all other infrared thermometers have a visible laser beam to show where the invisible infrared beam is directed. So without the laser beam to show the point where the infrared beam is directed the thermometer has to be used at close range. I wanted to use it under my camper that is being used through the winter. With foam insulation skirting all around the camper, I wanted to be able to point the thermometer through a small door in the skirting to measure the temperature of the black and gray water tanks. But without the laser beam I am not sure exactly where the infrared beam is landing. So I can only use it at range. For that reason I almost returned the unit.

Health Inspectors beware of this model.

This model not nearly as accurate as the model it replaced.

Great remove Temp sensor

Works great. I use it for measuring temperatures in buildings that are only partially heat to keep equipment from freezing. It helps me find points of air entry and I check critical parts of my pumping system to make sure they are not frozen.
