Use the smart testo 871 mould kit to detect mould-risk areas in buildings quickly and easily. The testo 605i thermohygrometer included in the kit transmits the room parameters via Bluetooth® to the testo 871 thermal imager. Mould-risk areas are shown in amber or red on the camera display (according to the traffic light principle). The thermal imager impresses with a thermal sensitivity of 0.09°C and its ease of use, in addition to its professional measuring cable with excellent image quality. The equipment can be transported safely and conveniently in the robust case.

• Impressive image quality: IR resolution up to 480 x 360 pixels through testo SuperResolution Technology and thermal sensitivity of 0.09°C for the display of small temperature differences

• Visualization of mould-risk areas with traffic light colours

• Including the testo 605i thermohygrometer: real time transmission of the ambient temperature and relative humidity readings to the thermal imager

• Smart: the free testo Thermography App enables you to write and send reports on site, as well as saving them online, and lots more
