- Infrared measurement with 1-point laser sighting and 6:1 optics ratio
- Display of differential temperature, such as between a window and air
- Hold function and min./max. values
- Display illumination
The testo 810 infrared thermometer allows for the simultaneous measurement of the air temperature and surface temperature of the object being measured – without contact. This infrared temperature measuring instrument automatically displays the temperature difference. This makes it particularly suitable for use in the heating, ventilation, and air conditioning trades.
