Model 1803
Water vapour in the range 0 - 1,000 ppm can be measures with this analyser using an electrolytic cell.
Water vapour is a notoriously difficult measurement to make as it adheres to stainless steel tubing, valves, filters etc. Diteco use chemically treated tubing to reduce the adherence of the water to the tubing.

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.
The benefits are as follows:
• Absolute Measurement - Calibration not required
• Built-In Sample System - Reduces installation costs
• Electronic Flow Control - Mass flow controller for improved accuracy
• Simple Cell Regeneration - Low cost of ownership
• Chemically Treated SS Tubing - Prevents moisture adhering to tubing walls
