Testo 872 Thermal Camera 320x240 with Super Resolution and Smartphone App

With the Testo 872, a thermal imaging camera has been developed that allows you to quickly and easily access professional technology. With the Testo ScaleAssist, Testo ɛ-Assist and IFOV display functions, you can not only avoid measurement errors and easily set the emissivity (ɛ) and 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 scale to the optimal values, excluding interpretation errors that can occur due to an incorrect setting of the scaling factor. Unwanted temperature extremes are automatically discarded from the image. Building pathologies are represented as such only if they are actually present. Infrared images thus become comparable despite different environmental conditions. A very important feature e.g. for before/after shots.

To obtain accurate thermal images it is important to set the emissivity (ε) and reflected temperature (RTC) of the object to be imaged in the camera. Until now this operation was very inconvenient and also rather imprecise from the point of view of the reflected temperature. A gap that has now been filled by the innovative ε-Assist Text function: Simply attach one of the supplied reference stickers ( ε-markers ) to 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: Always know what can be measured accurately from a given distance.

The thermal imager can connect wirelessly to the Testo 770-3 clamp meter and the Testo 605i thermo-hygrometer. The measured values of the two compact instruments are transferred to the thermal imager via Bluetooth. In this way, it is possible to quickly and clearly identify on the thermal image exactly where the damp spots of a building are located or with which load an electrical cabinet is operated.
