- 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
