Special Advantages N/A
  • Stable and accurate measurement results over the long term
  • High-precision measurement of relative humidity and process temperature, as well as calculation of various humidity variables such as absolute humidity [g/ m3]; moisture content [g/kg], or moisture content [ppmV/V]
  • Two freely configurable analog outputs, 4...20 mA
  • Modbus-RTU (RS 485)
  • Media-independent measurement, in non-corrosive gases
 		N/A
Typical Applications N/A Typical application is the measurement of residual moisture in:
  • Measurement of humidity in gas pipes or storage tanks
  • Moisture from phase change processes (evaporation)
  • Measurement of humidity in inert gas environments (e.g., nitrogen or argon)
  • Electronics production in an inert gas atmosphere
  • Laboratories with special gas requirements
