Art.Nr.: GMH3331-TFS-WPF4Produktbeschreibung
set GMH 3331-TFS-WPF4 consisting of:
- humidity/temperature and flow rate measuring device GMH 3331 (direct successor of GMH 3330)
- humidity/temperature sensor TFS 0100 E
- works calibration certificate WPF4 (~20 %, ~40 %, ~60 %, ~80 % r.h. increasing and decreasing)
- case GKK 3500
The GMH 33xx devices are universal precision hygrometers/thermometers with additional thermocouple input in one. The plug-in probes are exchangeable without recalibration, because the calibration data are stored on an integrated memory (TFS...). The thermocouple input T2 has been optimized to quickly acquire surface temperatures e.g. to indicate the dewpoint distance directly.
- calculation of dewpoint temperature, dewpoint distance and enthalpy
- additional temperature input (type K)
applications:
- heating / ventilation air conditioning (HVAC)
- indoor air, meteorology, laboratory, research and teaching
- energy assessment / optimization of buildings
- cause study at structural damage
