Use the smart testo 871s mold set to quickly and easily detect mold-prone areas in buildings. The included testo 605i thermo-hygrometer transmits room parameters via Bluetooth to the testo 871s thermal imaging camera. Mold-prone areas are displayed in orange or red on the camera screen (using a traffic light system). In addition to its professional measurement performance, the thermal imaging camera impresses with very good image quality, a thermal sensitivity of 0.08 °C, and user-friendly operation. The robust case allows for convenient and safe transport of the equipment.
