The DPME-G dew point meter uses a capacitive sensor. Its working principle is to measure the amount of trace moisture in the gas according to the change of the capacitance value of the water molecule. Continuous high-speed on-line analysis of trace moisture is achieved by using imported alumina or polymer film sensors and advanced digital processing technology.
