Uncover potential thermal bridges and mold risk

super easy to use. Best at gedämmtem light, then numerous measurement points are clear.
My carpenter as doorstep supplier I could convince them of the necessary adjustment work to seal the door immediately. Despite 2 super silicone seals there was demand. Had I otherwise probably not squandered.
The detector showed a very cold evening clear that the dew point has been reached in a corner.
-> LED turns red -> Ok is corrected.
Better you can not.
I have borrowed the device with colleagues and all who followed up the points in the house, one of which was always suspected that they cause problems. Consistently positive feedback!
