UNI-T UT301A+ Infrared Thermometer
UNI-T UT301A+ Infrared Thermometer is a durable and easy-to-use non-contact temperature measuring instrument that delivers high accuracy, 95% energy response, and excellent repeatability. It features adjustable high and low temperature visual and audible alarms, a fast response time of less than 250 ms, and supports five preset emissivity settings for accurate measurements on different surface materials. With lock measurement, MAX/MIN/AVG/DIFF hold functions, and a tripod mounting option, the UT301A+ is ideal for continuous temperature monitoring in power distribution, transportation equipment inspection, HVAC maintenance, vehicle diagnostics, and other industrial applications.
Features
- 12:1 distance-to-spot (D:S) ratio for accurate non-contact temperature measurements.
- Adjustable emissivity (0.1–1.0) for improved accuracy across different surface materials.
- High measurement accuracy of ±1.5°C for reliable temperature readings.
- User-configurable visual and audible alarms for temperature threshold notifications.
- High-contrast EBTN color display for clear visibility in various lighting conditions.
- Supports MAX, MIN, AVG, DIFF, and Data Hold measurement modes for comprehensive analysis.
