Designed for ease and accuracy, the PosiTector IRT includes a 5.7:1 distance-to-spot ratio, fast response (<500 µs), and adjustable emissivity settings. Data logging, USB/Bluetooth/WiFi support (in advanced models), screen capture, and alarms make it suited for thermal profiling and diagnostic tasks.

DeFelsko PosiTector IRT Infrared Thermometer

The PosiTector IRT integrates an IR sensor, protective housing, and user interface to deliver reliable surface temperature readings from a distance. It offers modes such as scanning statistics, trend indicators, and HiLo alarms. With traceable calibration and robust design, it is ideal for field inspection of structures and coatings.
