The thermal imager testo 881 with the best thermal sensitivity of < 50 mK provides highest image quality. This allows you to measure even the smallest temperature differences, and obtain high resolution IR images at any time. A wide-angle and a telephoto lens allow adaptation to the different sizes and distances of measurement objects.

1. Detector size 160 x 120 pixels
With 19,200 temperature measurement points, the measurement objects are detected in very good image quality, clearly and precisely.
2. SuperResolution technology (to 320 x 240 pixels)
SuperResolution technology improves the image quality by one class, i.e. the resolution of the thermal images is four times higher.
3. Thermal sensitivity < 50 mK
Thanks to an excellent temperature resolution of < 50 mK, even small temperature differences are visible.
4. Built-in digital camera with power LEDs
Parallel to the thermal image, a real image of each measurement object is also stored. The power LED’s guarantee optimum illumination of dark areas when recording real images.
5. Solar mode
For each measurement, the sun irradiation value can be entered into the camera. This value is stored for each thermal image.
6. Special measurement mode for detecting areas with danger of mold
Using the externally measured ambient temperature and air humidity, as well as the surface temperature, the humidity value of each measurement point is calculated and shown in the display as a real humidity image.
7. High temperature up to 550°C
With the high temperature option, the measuring range can be flexibly extended up to 550°C.
