Description
The testo 831 infrared thermometer enables rapid, precise surface temperature checks of individual food products and complete product pallets. Designed for the food industry, this handheld instrument delivers two measurements per second and supports multi-scanning of goods and refrigerated shelves. Its 30:1 optics allow accurate readings even at greater distances: at one metre the measurement spot diameter is only 3,6 cm, so smaller items such as yoghurt pots can be targeted reliably. A two-point laser marks the measurement circle, preventing mis-aiming. Users can set up to two alarm thresholds with optical and acoustic alerts, while hold plus min/max functions aid limit monitoring. The measuring range covers −30 °C for frozen goods through to +210 °C for hot displays. HACCP certified and supplied with a holster including belt clip for ready access, the pistol-grip unit from manufacturer Testo offers simple one-handed operation via a trigger. Battery powered with IP30 protection, it measures 38 mm × 75 mm × 190 mm and has a net weight of 0,365 kg.

Questions about testo 831 Infrared thermometer
What is this article?
testo 831 Infrared thermometer is the article on this page. Luminix Health distributes Testo for laboratory use. It sits in Infrared thermometers, inside Temperature measurement, in Lab instruments.
An infrared thermometer reads a surface by its radiation. The reading depends on emissivity: a shiny metal lies unless the setting is changed. It does not read the inside of a bottle. Distance and spot size decide which surface is actually measured.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
