Testo 835-H1 infrared thermohygrometer 0560 8353
Infrared thermohygrometer with variable emission factor, very high ratio of distance to the diameter of the measuring area (50:1) and the possibility to connect different K-type temperature probes.- 4-point laser marking for visual determination of the area to be measured.
- Min./Max. value fixation.
- Visual and acoustic alarm signal when measurements exceed preset value limits (both Min. and Max.).
- In addition to temperature and relative humidity, dew point can also be determined.
- Using the free software EasyClimate, it is possible to easily and conveniently analyze the measurement data.
- Various K-type temperature probes can be additionally connected (can be purchased separately).
