Feature: Versatile Infrared ThermometerInfrared technology makes it easy to safely measure the surface temperatures of both scorching hot and freezing cold objects, such as ovens, AC units, grills, car engines, and refrigerators. Backlit LCD DisplayOur IR thermometer (-58932F / -50500C ) equipped with backlit LCD screen, C/F units quick conversion, release trigger auto hold data, auto power off to save energy, low battery indication (2 x AAA battery included). Maximum Temperature ModeThe display will show the max temperature of the surface youre measuring. Non-Contact12:1 D:S, the laser temperature gun can accurately measure targets from a distance. Accurate MeasurementOur laser thermometer gun has an emissivity range of 0.1 to 1.0 for precise readings across different surfaces and conditions. For best results, the reader should be 14" away from the object. Do Not Use on HumansIt is intended for use on inanimate objects only. Measuring the temperature of a human or animal is unsafe.
