The Raytek MiniTemp thermometer, No. MT6, is a non-contact thermometer for automotive professionals. The MT6 can be used to spot cooling system faults, identify engine misfires, check for proper A/C performance, verify catalytic converter operation and more. The laser point sighting on the MT6 unit helps to direct measurements toward the target and the large back-lit display shows both the current and maximum readings simultaneously. This unit has a protective boot for added durability, an ergonomic design and reads temperatures from -20 to 932 degrees F (-30 to 500 degrees C).
