Cermet II is a reliable intelligent instrument used for online humidity measurement of gases in many applications. The Cermet II includes an advanced ceramic sensor from Michell and a display control unit, which can be connected by a cable of up to 1200 meters. Cermet II is easy to use and suitable for almost all humidity measurement applications. It can display multiple measurement units, such as ° C or ° F dew point, ppmV, Lb/MMSCF or g/m ³, with a dew point range of -100~+20 ° C dp, a maximum pressure resistance of 30 MPa (300 barg), and allows dynamic pressure compensation through signal input from a pressure transmitter (provided as an optional option). highlight Wide range ± 1.0 ° C accuracy Analog and digital outputs Pressure transmitter signal input Up to 4 channels of alarm relays Measurement units are optional Clear LED display
