Testo 871 240x180 Thermal Camera with Super Resolution and Smartphone App

With the Testo 871 , a thermal imager was developed that allows access to professional technology quickly and easily. With the functions Testo ScaleAssist , Testo ɛ-Assist and IFOV indicator you can not only avoid measurement errors and easily set the emissivity (ɛ) and the reflected temperature (RTC), but also optimally adjust the color scale in the building thermography sector.

With the Testo ScaleAssist function, the correct evaluation of building pathologies and thermal bridges becomes child's play. The function automatically sets the thermal image scaling to the optimal values, excluding interpretation errors that may occur due to an incorrect setting of the scaling factor. Unwanted extreme temperatures are automatically discarded from the image. Building pathologies are represented as such only if they are actually present. The infrared images thus become comparable despite the different environmental conditions. A very important feature eg. for before / after shooting.

To obtain precise thermal images it is important to set the emissivity (ε) and the reflected temperature (RTC) of the object to be imaged in the camera. Until now this operation was very uncomfortable and also rather imprecise from the point of view of the reflected temperature. A gap that has now been filled by the innovative Testo ε-Assist function: it is sufficient to apply one of the reference stickers ( ε-markers ) provided on the object to be measured. Thanks to the integrated digital camera, the thermal imager locates the adhesive, measures the emissivity and the reflected temperature and automatically sets both values.

IFOV indicator: to always know what can be accurately measured from a certain distance.

The thermal imager is able to connect wirelessly to the Testo 770-3 clamp meter and to the Testo 605i thermohygrometer . The measured values of the two compact instruments are transferred to the thermal imager via Bluetooth. It is thus possible to quickly and clearly identify on the thermal image where exactly the damp spots of a building are located or with which load an electrical panel works.
