GDS-68XP Natural Gas Odorant Monitor


The GDS-68XP Process Odorant Monitor for Natural Gas Streams uses highly reliable and low cost electrochemical sensors to directly measure mercaptans and other gases in a stream of 100% natural gas. The microprocessor-controlled sequencing system periodically samples the gas stream and stores the result while bathing the sensor is clean air. The GDS-68XP Process Monitor is an ideal alternative to expensive analyzers or once-a-day measurements using pull-tube technology.
