testo 810 - Infrared thermometer

Description

Product Overview
The Testo 810 is a compact and versatile 2-channel temperature measuring instrument designed to measure air temperature and surface temperature simultaneously. Using an integrated infrared sensor for non-contact surface measurement and an internal NTC sensor for air temperature, the instrument automatically displays the temperature difference between air and surface.

Its pocket-sized design makes it easy to carry and ideal for quick checks in HVAC, building inspection, and maintenance applications. The infrared measurement is supported by a 1-point laser sight and adjustable emissivity, ensuring accurate readings on different surfaces.
