The Testo 875-1i Thermal Camera can be used to quickly and reliably detect thermal anomalies. The Thermal Imager is suited to a wide range of professional applications making it perfect for the heating engineer looking to utilise the power of thermal imagingWith a thermal resolution of <50 mK, laser pointer and integrated digital camera, this thermal imager allows you to quickly discover weak spots and assess energy efficiency in buildings. The Testo 875 Thermal Camera is fully equipped for detecting air leaks, heat loss and moisture when performing building diagnostics. The 875-1i Thermal Imaging Camera is a diagnostic tool in the HVAC industry where it is frequently used to trace heating system pipe work, assessing radiator performance and checking under floor heating. Super Resolution Technology is supplied as standard to increase the thermal resolution by four times, resulting in a 320x240 pixels resolution and a huge improvement in thermal image quality, detail and accuracy .
