No contact with the measurement object directly, ensuring safety and health when measuring. Whether you are cooking or making crafts when you need the thermometer will not contaminate your masterpiece, and also prevent you from getting burned or frostbite. Features: Higher AccuracyCompared with most other thermometers, the laser caliper has a point-to-point ratio of 12:1, which means it can accurately measure targets that are farther away. Easy to UseSimply scan the surface of your object, hold down the trigger of the infrared thermometer gun, and release to get live temperature readings anywhere between -50C~400(-58~752). User-friendly designWith 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. Wide Range of ApplicationsInfrared technology makes this temp gun convenient to measure the surface temperature of inanimate objects: 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.
