The non-contact thermometer UT303D+ is a durable and easy-to-use infrared thermometer with high accuracy / energy (95%) / repeatability. It has an adjustable high and low temperature visual/audio alarm that responds faster than 250ms, helping you quickly detect anomalies. You can preset and save 5 sets of emissivity values ​​and quickly switch the emissivity according to different surfaces to get more accurate results. With lock measurement, MAX / MIN / AVG / DIFF hold and tripod mount, the UT303D+ is ideal for processes that require temperature monitoring. The UT303D+ can be used for power distribution / transmission equipment inspection, HVAC / equipment maintenance, vehicle troubleshooting and other applications. EBTN color backlit display. Can be attached to a tripod with a standardized threaded hole.

Dual Laser
Principle: the thermometer uses two laser lines that converge at the point where the thermometer measures the temperature. The lasers intersect exactly at the point of measurement, allowing for precise targeting.
Advantages: the dual laser helps to focus on a specific point, which is useful for measuring smaller or more distant areas.
Use: suitable for applications where high accuracy is needed and where the measured area is smaller (e.g. industrial inspection or measurement of small components).
