The operating principle of the moisture analyser is as follows. Sample is passed through a phosphorous pentoxide (P₂O₅) electrolytic cell of proven performance at a flow kept constant using a mass-flow controller. All of the moisture in the sample is continuously absorbed on to the P₂O₅ and electrolysed by passing a current through the platinum wires. According to Faraday's Law, the moisture content of the gas is proportional to the amount of current required for electrolysis.
