UNI-T UT301D+ infrared thermometer

The UNI-T UT301D+ infrared thermometer measures temperature without contact across a wide range from -32 °C to 600 °C, making it suitable for maintenance, diagnostics and equipment monitoring. According to the manufacturer, readings appear in under 250 ms and repeatability is 0.7%, so deviations can be spotted quickly. Accuracy depends on the temperature: above 0 °C it is ±1.5 °C or ±1.5%, while below freezing the error margin grows according to ±(1.5 °C + 0.1 °C/°C).

The adjustable emissivity from 0.1 to 1.0 helps adapt measurements to different surfaces, and five settings can be saved. MAX, MIN, AVG and DIFF modes, together with the HOLD function, make it easier to analyse temperature changes and keep a reading on screen. The device features a colour display, backlight, and adjustable visual and audible alarms when preset thresholds are exceeded.

The package includes the thermometer, a 9 V battery, a carrying bag and the user manual. The unit weighs 204 g.
