Description
testo 831 infrared thermometer, Emissivity adjustable, incl. leather protective cover, calibration protocol, batteries.
For non-contact temperature measurement of surfaces, even of small objects. IR measurement fast and precise, even at large distances. Larger measuring tasks are completed quickly and efficiently (measuring cycle: 2 measurements per second). Ideal for the food sector (HACCP-certified).
- Two-point laser spot marker for targeting the measuring point (spot diameter at one metre 3.6 cm)
- Visual and audible alarm when limits are exceeded; limits freely selectable
- Min./max. value display and hold function (for recording a measured value)
- Optimal for long distances thanks to 30:1 optics
- Adjustable emissivity

Questions about testo 831 infrared thermometer, Emissivity adjustable, 1 unit(s)
What is this article?
testo 831 infrared thermometer, Emissivity adjustable, 1 unit(s) 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.
Which category should I open next?
The category is Temperature measurement. The sub-category is Infrared thermometers. The catalogue is Lab instruments.
Shelves beside this one are Laboratory glass thermometers, Temperature probes & sensors, Hygrometers & humidity meters, Data loggers, Temperature measurement accessories and Digital thermometers.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
