Professional mould risk detection with Testo.

The precise visualization of mould danger is of great significance in building diagnosis, as lacking or inaccurate analyses can cause damage with serious consequences.

In order to avoid this risk, potential risk spots have to be identified as exactly as possible.

With a thermal imager and a wireless humidity probe from Testo, you can do this professionally, easily and absolutely reliably.

The challenge

Mould growth in a corner
  • Mould can form anywhere where too much moisture occurs e.g. on walls or ceilings.
  • Causes for this can be insufficient ventilation or cold bridges plus humid ambient air.
  • Many damp spots are not identifiable with the naked eye, and can only be detected with professional measurement technology.

The solution

How to measure mould danger
  • Thermal imagers with a humidity mode and optional thermohygrometer exactly and reliably visualize mould risk.
  • The required indoor air temperature and indoor air humidity readings can either be manually entered or are wirelessly transmitted to the thermal imager from the optional testo 605i thermohygrometer.
  • Mould-risk areas are clearly presented directly in the thermal imager using a traffic-light system.
