UNI-T UT300S Handheld Digital Non-Contact IR Infrared Thermometer Temperature Gun with LCD Backlight

The UT300S from UNI-T is an infrared thermometer that can measure the temperature of surfaces without having to touch it. With a deviation of only 2%, this thermometer is very accurate and very affordable. The thermometer has an adjustable’ emissivity’ which makes it possible to compensate for the material being measured. The meter can measure temperatures from -32°C to 400°C and has a measuring point-size ratio of 10:1. This means that at a distance of 10 metres, the thermometer performs a measurement over a surface with a diameter of 1 metre.

The meter’s display is equipped with a backlight, so you can also read off the screen in the dark. It is also possible to display and maintain Min and Max values during measurements. You can also switch between Celsius or Fahrenheit with just one touch of a button. The laser pointer can also be switched on or off if necessary.

UT300 series infrared thermometers are lightweight and small. Objects can be quickly and accurately measured from a distance with 0.1°C resolution. These devices consume very little power, suitable for indoor and outdoor use.
