UNI-T UT303D+ Infrared thermometer

The Uni-T UT303D+ is a non-contact infrared thermometer for measuring surface temperatures from -32 °C to 1300 °C. Two laser pointers make it easier to identify the measurement spot precisely, and a response time of 250 ms gives quick readings. Accuracy is ±1.5 °C or ±1.5% above 0 °C; below freezing, the error is calculated with the formula ±(1.5 °C + 0.1 °C/°C).

The adjustable emissivity from 0.1 to 1.0 allows readings to be adapted to different materials. A colour EBTN display shows the values clearly, while the MAX, MIN, AVG and DIFF analysis functions and storage of up to 99 measurements with date and time simplify record keeping. The HOLD function, audible and visual alarms and a backlight support use in varying conditions.

Weighing 310 g, the device has a distance-to-spot ratio of 30:1, allowing measurements from a greater distance. It carries CE and UKCA marking. The package includes a 9 V battery, a carrying bag and a user manual.
