Developed for the natural gas and LNG industries, our Hygrometer Validation System provides a complete package of dry gas purge, master reference hygrometer and a suite of portable hygrometers, allowing confident confirmation of critical zero measurement values in both the portable units and the plant online analysers.

MCM’s ATEX-certified portable hygrometers are selected because of their rapid speed of response and ability to provide traceable measurement against a verified standard. The Hygrometer Validation System has therefore become the first choice for laboratory operators on projects around the world – a first line of defence for protecting plants from high moisture events, and a key troubleshooting tool for those occasions where process upset cannot be prevented.

Widely used by clients where process gas specifications are at “trace” levels (e.g. <1 ppmV), a single Hygrometer Validation System can support multiple online plant moisture analyser systems. Because of the rapid sensor response of the MCM portable hygrometers, the operator can make many process validation measurements in a short period of time. The total number of MCM portable hygrometers required is flexible and can be specified to suit the plant conditions.
