UT300S is an infrared thermometer that determines temperature of objects through their emitted radiation. Its main function is to measure temperature from a distance. The UT300S consumes very little power and helps users to measure temperature quickly and accurately. The digital non-contact infrared thermometer is a reliable device used to measure the surface temperature of an object safely and quickly. Wide temperature measurement range makes it applicable for various hot, hazardous or hard-to-reach objects.Features:Handheld infrared thermometer for non-contact measurement of object surface temperature.Adjustable emissivity from 0.10 to 1.00.Optional temperature units: Celsius(°C) and Fahrenheit(°F).Maximum and minimum value display. Long press the measuring key under MAX mode and move the meter at the target area, the meter will only display the value greater than the current value; long press under MIN mode it will only display the value less than the current value.Can set upper and
