Description
Uni-T UT303D+ Infrared Thermometer
The Uni-T UT303D+ infrared thermometer is a precision device for non-contact surface temperature measurement over a wide range from -32°C to 1300°C, equipped with a dual laser for easy and accurate targeting and a fast response time of 250 ms. It offers high measurement accuracy of ±1.5°C or ±1.5% for temperatures ≥0°C, while for sub-zero temperatures, the error is calculated using the formula ±(1.5°C + 0.1°C/°C). The model features adjustable emissivity (0.1–1.0), a clear color EBTN display, analysis functions (MAX/MIN/AVG/DIFF), and the ability to store up to 99 measurements with date and time, making it an advanced tool for precise non-contact measurements.
Functionality and Measurement Precision
The Uni-T UT303D+ is designed for convenient and accurate operation—thanks to its 30:1 D:S ratio, it enables measurements from a greater distance while maintaining high precision. The device offers visual and audible alarms, a result hold (HOLD) function, data logging, and the ability to perform scheduled measurements. Its rugged construction, resistant to drops from heights of up to 1 meter, ergonomic housing, and backlight make the device well-suited for various working conditions.
