The Raytek MiniTemp IR thermometers, Nos. MT2 and MT4, are non-contact, infrared thermometers for professionals in any industry where they need to accurately and safely measure surface temperature. These thermometers can be used to measure temperatures on hot and hard-to-reach places or on moving parts. The laser point sighting on the MT4 unit helps to direct measurements toward the target and the large back-lit displays on both models show the current and maximum readings simultaneously. These units read temperatures from 0 to 750 degrees F (-18 to 400 degrees C).
