The sensor contains a highly hygroscopic solid electrolyte that absorbs moisture present in the sample and creates an electrolysis current directly proportional to the moisture content.

A knowledge of the gas flow rate and the current in the cell gives an absolute measure of the moisture contained in the sample gas. The sensor is suitable for all corrosive & other gases and materials in contact with the sample are glass / teflon, platinum or rhodium, and the selected material of the sensor holder.

The special transfer of the sample-gas through the sensor, combined with a high quality surface provides fast response and minimizes the tailing effect. This benefit is especially important when monitoring low ppm-concentration. Sensor is a regeneratable and can be expedileously done at site.
