The testo 875 and 881 Imagers are innovative
new imagers/cameras that let you actually see the heat…

•  That seeps through walls, doors and windows due to 
   poor construction, insulation or design
•  From a faulty electrical circuit about to fail or cause a fire…
•  From friction in a failing bearing of a motor or compressor
•  Or the cooling created by moisture trapped in a wall  
   or floor that starts mold growth

Superlative image quality ensures reliable diagnoses even for the smallest temperature differences

With advanced electronics and a thermal resolution 0.1°C and better, testo imagers deliver high definition images which satisfy even the most demanding user. A standard wide angle and an optional telephoto lens enable adaption to the different sizes and distances  of measurement objects. Most models inlude an integrated digital camera, linking visual and IR images for fast and easy documentation. An optional removable protective lens prevents damage to the valuable optics.
