Smart Mould Kits
With automatic calculation of risk of mould
Mould develops long before it’s visible, and by the time you can spot it, it has often already spread beneath the surface. Early detection helps identify hidden mould risks before they turn into costly damage.
By connecting the testo 605i thermohygrometer to our thermal camera, you can activate humidity mode to instantly highlight areas at risk of mould.

Moisture
Moisture inside buildings can lead to mould caused by construction defects or improper use. Testo’s patent-pending humidity image shows relative surface humidity directly in the thermal image, helping you detect mould risk early—before it becomes visible.
The calculation combines surface temperature from the thermal camera with ambient temperature and humidity data from the testo 605i, which is transmitted automatically via Bluetooth, eliminating manual data entry.
The humidity palette on Testo thermal imagers then uses a clear traffic-light principle to visualise risk zones:
Green = no risk
Amber = caution, mould formation possible
Red = WARNING! Risk of mould
