UNI-T UT303A+ Infrared Thermometer
The UNI-T UT303A+ Infrared Thermometer is a high-performance non-contact temperature measurement instrument that allows users to safely measure the surface temperature of hot, moving, or hard-to-reach objects without physical contact. Featuring a wide measurement range, fast response time, and 30:1 distance-to-spot ratio, it is ideal for maintenance engineers, electricians, HVAC technicians, automotive professionals, and industrial inspectors.
Equipped with a high-contrast color EBTN display, adjustable emissivity, laser targeting, audible and visual high/low temperature alarms, and MAX/MIN/AVG/DIFF measurement modes, the UT303A+ provides reliable and accurate readings across a variety of surface materials. Its ergonomic design, tripod mounting capability, and rugged construction make it suitable for both field service and workshop environments. This device is intended for measuring surface temperatures and is not a medical thermometer.
Features:
- ±1.5℃ temperature measurement accuracy.
- User defined visual and audio alarm.
- High contrast EBTN color display.
- MAX/MIN/AVG/DIFF/Hold modes.
- Dual lasers (UT302D+/UT303D+).
- Temperature recording up to 99 groups (UT302C+/UT303C+/UT302D+/UT303D+).
- Date/time display (UT302C+/UT302D+/UT303C+/UT303D+).
- Time scheduled measurement (UT302C+/UT303C+/UT302D+/UT303D+).
