- Non-contact measurement of surface temperature, ideally suitable for the food sector
- 2-point laser measurement point marker and 30:1 optics
- Exact measurements even at greater distances
- Large measuring range from -30 to +210 °C
- Hold-function and display of min./max. values
- Two adjustable alarm limit values
- Also available as a set with the core thermometer testo 106
The testo 831 is an infrared thermometer for distance measurement. Thanks to its 30:1 optics, the measurement point diameter is only 3.6 cm at a distance of 1 m. This allows smaller objects such as yoghurt pots to be conveniently measured at a distance. Thanks to a 2-point laser marker, the diameter of the measurement point is displayed exactly, avoiding measurement errors. At two measurements per second, the testo 831 is so fast that scans of palettes or refrigerated shelving can be carried out.
Set testo 831 and testo 106 For certain temperature measurements in the food sector, it is necessary to carry out an additional core temperature measurement. For this purpose, Testo offers an economic set consisting of the testo 831 and the proven core thermometer testo 106.
