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 backlighting ensure the device performs well in various working conditions.
Proven quality and refined details
The UT303D+ model is CE and UKCA certified, confirming compliance with European quality and safety standards. The design incorporates a dual laser system (Dual Laser) that precisely marks the measurement area, enhancing the user’s control and accuracy. Thanks to its refined technical specifications, analytical functions, and data logging capabilities, the device is a robust and reliable tool for those seeking accurate and repeatable measurement results.
