The Cell (sensor) of the MEECO AquavoltTM is composed of two sets of electrodes embedded in a insulating glass tube, which are coated with P2O5 film.When the sample gas passes through the Cell at a constant velocity, the Cell’s P2O5 membrane absorbs water from the gas. When the two sets of electrodes are energized, the absorbed water molecules are electrolyzed, generating a current.According to Faraday’s principle, the moisture absorbed by the Cell can be converted by current to accurately measure the moisture content of the sampled gas.
