Compared to most other thermometers, the point-to-point ratio of the laser caliper is 12:1, which means it can accurately measure farther targets. Easy to use, simply scan the surface of the object, hold down the trigger of the infrared thermometer, and release it to obtain real-time temperature readings between -50 ~600 (-58~1112). User friendly design with data retention function, unit switching (C/F), and temperature calibration range between -3C and 3C. Each infrared thermometer has a large backlit LCD screen that can easily read temperature even in the dark, and automatically shuts off for 12 seconds to extend battery life, so you won't accidentally lose power. The wide application range of infrared technology makes this temperature gun easy to measure the surface temperature of inanimate objects: cooking, baking, grilling, frozen food, fried food, car maintenance, completing HVAC projects, plantations, brewing, water temperature measurement, electrical appliances, etc. Not suitable for humans. This infrared thermometer is an industrial thermometer and cannot be used to measure body temperature. The reading measured by a thermometer is the surface temperature of objects and liquids, and cannot measure the internal temperature, so the measured temperature of people or animals may not be accurate. gauge Battery: 2 1.5V AAA batteries Product size: 145 * 78 * 43 millimeters/5.71 * 3.07 * 1.69 inches Product weight: 107 grams/3.77 ounces Packaging weight: 159 grams/5.61 ounces Packaging size: 19.5 * 11.5 * 5 centimeters/7.67 * 4.53 * 1.97 inches Packing list: 1 * Infrared thermometer 1 * User Manual (English)
