testo 885 Thermal Imaging Camera – Available for purchase from Ashtead Technology.

The thermal imager testo 885 is the professional measuring instrument for the high-precision detection of anomalies and damage to building shells or interiors. The high-quality infrared measurement system means that energy losses or thermal bridges in building shells can be reliably detected, enabling comprehensive energy consultations to be carried out. Indoor leaks can be reliably located, without needing to dismantle cable or pipeline systems.

The intuitive testo 885 with its rotating handle, fold-out display and lots of helpful functions, such as panorama image assistant and autofocus, makes it is possible to carry out both quick on-site checks as well as comprehensive energy consultations with professional reports simply, reliably and professionally.
