Testo 872 - thermal imager

The Testo 872 thermal imager is ideally suited for professional industrial and building thermography - at the same time, it ensures your work is both quick and easy. It is versatile to use, for example in industrial and mechanical maintenance or for detecting structural defects. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, Testo ɛ-Assist and Testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (ɛ) and reflected temperature (RTC) for building thermography, but also of thermal image scale.

Key Features: Testo 872 - thermal imager

Highest image quality: IR resolution of 320 x 240 pixels, via integrated testo SuperResolution Technology 640 x 480 pixels
Precise measurement: thermal sensitivity of 0.06°C
Smart and wireless: use your mobile device with the free testo Thermography App and wirelessly transmit readings from the testo 770-3 clamp meter and the testo 605i humidity measuring instrument (both available separately)
Integrated laser marker – can also be precisely visualized as a measuring point in the thermal image
