Applications

Location of thermal bridges and mold or corrosion formation

With the testo 835-H1, you can identify thermal bridges (places on walls, floors and ceilings where there is a greater outflow of heat) for early detection or identification of structural defects, energy loss and places where there is a risk of mold / moisture formation. the long range 50-1 optics provide spot accuracy for smaller mechanical components
Advantages of the testo 835-H1:

Fast detection of thermal bridges by scanning the walls, even at great distances
Measurement of the dewpoint, dewpoint distance and aw value (surface moisture) to assess conditions of the room and wall
Saving the data for documentation and comparison with previous measurements in order to evaluate corrective measures
