Description:
The testo 872 thermal imager stands out thanks to its resolution of 320 x 240 pixels, an excellent thermal sensitivity, numerous innovative functions, smartphone connection via the testo Thermography App and the best price-performance ratio of its class. For even more meaningful thermal images, the thermal imager testo 872 also wirelessly integrates the measurement values of the clamp probe testo 770-3 as well as the thermohygrometer testo 605i (both available as an option).
- 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
The testo 872 thermal imager gives you the best possible support for your work in professional industrial and building thermography. Take thermal images quickly, reliably and smartly with the highest image quality, very good thermal sensitivity and innovative functions. The case supplied with the thermal imager means it can be conveniently transported, so it is always there for you when needed.
