Release the trigger to stop. Accuracy Distancetospot ratio is 12:1, allowing accurate measurements on targets farther away than many other thermometers. Wide Applications Infrared technology makes it convenient to measure surface temperatures of inanimate objects across many tasks, including cooking, baking, grilling, monitoring frozen or fried foods, automotive work, HVAC projects, plantation and winemaking environments, water temperature measurement, and household appliances. UserFriendly Design Features a hold data function, easy unit switching between C and F, and temperature calibration from 3 C to 3 C. The handheld infrared thermometer includes a large backlit LCD screen for clear readings in low light, and a 12second autooff to extend battery life.
