    DPM-16H

    Function
    The meter uses the electrolytic method to measure the moisture content or dew point of non-corrosive gas or acid gas.


    Principle
    The coil-like double platinum wire and its gap (less than 20um) constitute an electrolytic cell. Phosphorus pentoxide in the gap between platinum wires absorbs trace water to produce phosphoric acid and generates a weak current. The current is proportional to the amount of water absorbed. The dew point or trace water content is calculated according to the measured current.
