Product Description
The temperature measuring instrument has cross laser marking and switchable optics for far-field and close-focus measurement. The infrared thermometer is therefore ideally suited for non-contact measurement of surface temperatures, both at short and long distances.
Areas of application for the testo 845 infrared thermometer
Industrial applications:
Detection of excessively high temperatures on switching cabinetsTemperature measurement on refrigeration unitsChecking and recording temperature values on generators and drivesTemperature checks on running rubber tyresTemperature measurement on plastics in the drying process
Applications for building services / air conditioning technology:
Checking the temperature on ventilation ductsDetermining heat profiles and thermal insulation in buildingsLocation of cold bridges and insulation weak points
Applications in heating engineering:
Surface measurement on radiators, painted heating pipesMeasurement of floor coverings to locate heating pipes
The advantages of the testo 845 infrared temperature measuring instrument
The testo 845 infrared temperature measuring instrument enables you to measure surface temperatures reliably and quickly - thanks to a reference accuracy of ± 0.75°C and fast measuring technology with 100 ms scanning.
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.
