BETTER ACCURACY: The distance to spot ratio is 12:1, which means the 1080 Laser Handle can accurately measure targets at greater distances than most other infrared thermometers; FASTER TARGET: Measure surface temperature ranging from -58 to 1022/ -50 to 550, you can choose the unit of /; Response time: 500Ms; A built-in laser gives you the precision to focus on the exact space you want to measure ADDED FEATURES: The LCD display is backlit, also has a function auto shut-off to extend battery life and features a low battery indicator so you never accidentally run out of juice (battery included) NOTE : The thermometer cannot measure the internal temperature of an object; The temperature readings of these devices are inanimate objects, the temperature measured for humans or animals will not be correct; FDA, FCC, CE compliance; Class 2 laser, optical power 0. 5-0. 9MW NOTE: For best accuracy, the distance between the thermometer and the measuring object should be approximately 14.17 inches (36 cm). Material type: plastic. Storage temperature: -20-50 (-4-122) VERSATILE DESIGN: Infrared technology makes this thermometer convenient for measuring the surface temperature of various objects, especially temperatures above boiling points and below freezing points; Use it when cooking and barbecuing, performing auto maintenance, doing home repairs and a host of other tasks 1080 Laser Thermometer Digital Infrared Thermometer Gun Temperature (-50550)
