– the thermal imager for daily use
The thermal imager testo 875 is the reliable, solid tool for your
daily use. With a temperature resolution of < 80 mK, exchangeable lenses and an integrated digital camera, you discover
weak spots in buildings quickly and securely with the thermal
imager testo 875. You localize leakage precisely, and detect
defective insulation directly.
For you, that means: You see more and have more reliability
when thermographing!

High image quality due to NETD < 80 mK
Thanks to a temperature resolution of < 80 mK, even the smallest
temperature differences are visible with the testo 875.
Exchangeable lenses
A wide-angle and a telephoto lens allow you the adaptation to the
very different sizes and distances of measurement objects.
Integrated digital camera
With the testo 875, you can store a real image of every measurement site parallel to the infrared image.
Automatic Hot/Cold Spot Recognition
Critical temperature stati are directly displayed using the automatic
Hot-Cold-Spot recognition
Lens protection glass
The germanium lens protection glass protects the optics from dirt
and scratching.
