UNI-T UT309E | Professional Infrared Thermometer

The UNI-T UT309E Professional Infrared Thermometer is the higher-range model in the UT309 rugged series, designed for industrial technicians, maintenance engineers, HVAC users, transport equipment teams and instrument repair work. It measures -35°C to 850°C, offers 20:1 D:S ratio, adjustable emissivity, dual laser targeting, 250ms response, high/low alarm, MAX/MIN/AVG/DIF mode, lock measurement, data hold and LED backlit display. UNI-T lists the UT309 series as IP65-rated and 3m drop-proof.

Pro Tip

Use the 20:1 optical ratio for safer measurement of hotter or harder-to-reach surfaces, while keeping the target larger than the spot size. Buy UNI-T UT309E from Kamadi Pakistan for rugged high-range temperature inspection.

Buyer’s Selection Guide

Choose the UT309E if you need the highest UT309-series range, longer D:S ratio and rugged IP65/3m-drop construction. It is suitable for tougher industrial environments and higher-temperature inspection points.
