PRODUCT DESCRIPTION
The TH-8859 is a handheld gun-type infrared thermometer for non-contact surface temperature measurement from −20 to 420°C. An 8:1 distance-to-spot ratio and 500 ms response let technicians scan motors, panels and products quickly without contact or shutdown.
Fixed 0.95 emissivity suits most organic and painted surfaces, and the 140 g pistol-grip body is built for routine inspection rounds.
