<p>User-friendly With hold data function, unit switching (C/F), temperature calibration range between -3C ~ 3C. Each IR temperature gun has a large backlit LCD screen for easy temperature reading even in the dark, and 12 seconds auto-off to prolong battery life so you won't run out of power accidentally.Ease of Use Effortlessly scan the surface of your target, press and hold the trigger on the infrared thermometer gun, and release to instantly obtain live temperature readings spanning from -50C to 600C (-58F to 1112F).Emissivity Calibration ModeFor increased accuracy, easily change the emissivity from 0.11.0 by holding the left and right buttons according to different materials to get the most accurate value. For normal household use, we recommend using 0.95 emissivity.Versatile DesignInfrared technology makes it to measure the surface temperature of various objects especially temperatures above boiling points and below freezing points. Use it for cooking, baking, grilling, frozen food, fried food, car repair, completing HVAC projects, plantation, winemaking, water temperature measurement, appliances, etc.Not Suitable for Humans This infrared thermometer gun is an industrial thermometer, it cannot be used to measure body temperature. The reading measured by the temperature measuring gun is the surface temperature of objects and liquids, and cannot measure the internal temperature, so the temperature of people or animals measured will be inaccurate.High Accuracy DESOMIYE laser thermometer gun adopts the latest high-sensitivity temperature sensor, which can measure the temperature range of -50C~600C (-58F~1112F) in only 0.5 seconds. For best results, the reader should be 14 inches away from the object.</p>
