UNI-T UT305S Professional Infrared Thermometer 2000°C with USB Data Logger

UNI-T UT305S Professional Infrared Thermometer 2000°C in Sri Lanka

Ultra-High-Temperature IR Thermometer with 50:1 D:S Ratio, 99-Set Data Logger and USB Output

The UNI-T UT305S Professional Infrared Thermometer delivers non-contact temperature measurement up to an exceptional 2000°C — the highest range in the UNI-T infrared thermometer series. Engineered for Sri Lanka's most extreme industrial temperature environments including steel processing, glass furnaces, induction heating, and high-temperature ceramic and refractory inspection, it combines a 50:1 distance-to-spot ratio with 99-set onboard data storage and USB data transmission for complete process temperature documentation.

Explore our full range of Infrared Thermometers – non-contact, laser, and industrial temperature meters in Sri Lanka!

With ±1.0°C measurement accuracy — the tightest specification in our UNI-T IR range — and a single Class 2 laser for precise targeting, the UT305S enables safe, accurate readings on molten surfaces, glowing refractory linings, and extreme-heat process targets from a fully protected standoff distance. Its USB output allows direct data transfer to PC for process analysis, compliance documentation, and quality system reporting.
