Digital Infrared Thermometer Laser Temperature Meter Industrial Non-contact IR Pyrometer Imager Gun -50-1600C (-58F~2912F) Feature Smarter Measurements: Accurately and quickly measures surface temperatures, ambient temperature and humidity within 0.5 second, Compared to most of the thermometer on the market, it can be able to measure more farther distance and show you the measurement area of the objects and different data directly. Added functions: the LCD screen is backlit, also has an auto-off function to extend the battery life, and features a low battery indicator. Storage Temperature: -20-50 (-4-122). Operating Temperature-0-50 (50-122). Versatile design: infrared technology makes this thermometer handy to measure the surface temperature of various objects especially temperatures above boiling points and below freezing points; use it when you are cooking and barbequing, performing auto maintenance, doing home repairs, and a host of other tasks. Note: the thermometer can't measure the internal temperature of an object; temperature readings from this devices are inanimate objects, the measured temperature for humans or animals will not be correct.
