Popis výrobku

The temperature measuring instrument is ideally suited for non-contact measurement of surface temperatures, both at short and long distances. And surface moisture can also be assessed using the infrared thermometer, thanks to the integrated humidity module.

Areas of application for the testo 845 infrared thermometer with humidity module

Applications for building services / air conditioning technology:
  • Early detection of mould: fast scanning of walls using non-contact measurement to assess the room and wall conditions, discover thermal bridges and detect mould
  • Checking the temperature on ventilation ducts
  • Determining heat profiles and thermal insulation in buildings

Industrial applications:
  • Temperature measurement on switching cabinets, refrigeration units, generators and drives, along with plastics in drying processes

Applications in heating engineering:
  • Surface measurement on radiators, painted heating pipes
  • Measurement of floor coverings to locate heating pipes
 

The advantages of the testo 845 temperature measuring instrument with integrated humidity module

The infrared thermometer calculates the surface moisture from the surface temperature and dew point of the air. This means that ceilings and walls that are at risk of developing mould can be more quickly located.

Far-field measurement means that surface temperatures can be measured very precisely at a great distance from the measurement object. At a distance of 1.2 m from the measurement object, the measuring spot diameter is only 16 mm. Bright cross-laser marking is used to indicate the real measuring spot.
For measurements a short distance from the measurement object, the close-focus optics provide a measuring spot diameter of only 1 mm at a distance of 70 mm. In the process, two laser points mark the measuring spot.
In order to switch from far-field to near-field (close-focus) measurements, simply move the slide switch on the infrared temperature measuring instrument to the appropriate position.

As an option, you can carry out additional measurements, such as determining the emission level, via attached temperature probes (the probe socket is located underneath the handle) for an even more accurate measurement result.
