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. Target quicker: measure surface temperature ranging from -50 ~ 550 (-58~1022), you can choose the unit from / ; response time: 500Ms; a built in laser gives you the precision to hone in on the exact space you want to measure. Added functions: the LCD screen is backlit, also has an auto-off function to extend the battery life, and features a low battery indicator. 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.
