Location of thermal bridges and mould 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 than at points nearby, mainly due to structural defects) for early detection or identification of structural defects, energy loss and places where there is a risk of mould formation.

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
