FAS-W Humidity Analyzer

FAS-W humidity analyzer is an automatic condensation hygrometer designed for measuring volume ratio of moisture in gas and dew point temperature under pressure up to 10 MPa.

The analyzer comes with an absolute gas pressure sensor and can recalculate the dew point into the moisture volume ratio.

The measured and calculated humidity values can be communicated to the upper level via both current (4…20 mA) and digital output RS-485 (Modbus protocol).
