Cermet II Intelligent Dew Point Meter
Cantilever beam sensor
Product details


Cermet II is a reliable intelligent instrument used for online humidity measurement of gases in many applications. The Cermet II includes a Michell ceramic sensor and a display control unit, which can be connected by a 1200 meter cable. The Cermet II is easy to use and suitable for humidity measurement applications. It can display multiple measurement units, such as ° C or ° F dew point PpmV, lb/MMSCF or g/m ³, dew point range of -100~+20 ° C dp, high pressure resistance of 30 MPa (300 barg), and allows dynamic pressure compensation through signal input of pressure transmitter (provided as an optional part).
