The Testo 810 can measure infrared (IR) surface temperature as well as ambient temperature thanks to its built-in NTC sensor. This mechanism allows you to quickly and accurately compare the room temperature with the surface temperature of a fan, vent or window.

Infrared measurement is performed with a single-point laser sight and 6:1 optics. Differences between surface and air temperatures are automatically displayed. The Testo 810 is very handy, ergonomic and easy to use.
