UNI-T UT309C Infrared Thermometer -35°C to 600°C with Dual Laser

The UNI-T UT309C is a professional infrared thermometer designed for non-contact temperature measurement across a wide range of applications. With a measurement range of -35°C to 600°C (-31°F to 1112°F) and a 20:1 distance-to-spot ratio, it delivers accurate readings from a safe distance. The dual laser pointers help identify the measurement area, while the adjustable emissivity (0.1 to 1.0) ensures precision on various surfaces.

Advantages

Fast response time of ≤250ms, color EBTN LCD with backlight for clear visibility, and multiple measurement modes including Max/Min/Avg/Diff. High and low temperature alarms with audible and visual alerts enhance safety. The rugged design withstands drops from up to 3 meters, making it ideal for industrial environments.
