When critical moisture analysis can only be made in a hazardous area, then the MicroView Mini Ex-d Hygrometer System delivers MCM’s leading-edge performance in a straightforward, ready-to-install package.
Ideally suited to any hazardous area process application that requires precise moisture control in the sub parts per million [ppmV] range, not only does the MicroView Mini Ex-d Hygrometer System deliver rapid and reliable analysis, it is also a dream for the process engineer and instrument technician. Ready to install direct from the box, the analyser has no complex setup, commissioning or operational requirements and is completely self-managing in all aspects of routine use.
Compared to alternative hygrometers that require detailed programming of instrument parameters, precise control of sample conditions and inefficient maintenance interventions, the MicroView Mini Ex-d Hygrometer is the very definition of a plug-and-play analyser solution.
For applications requiring the utmost control, or where the presence of contaminants in the sample gas can be detrimental to the measurement, the MCM Auto-Zero System range of hygrometers provide high precision online analysis on 24/7 basis. A cost-effective solution for heavier hydrocarbon streams, or dehydration processes utilising glycol contactors, these fully automated analyser systems reduce the necessity for routine operator intervention and maintenance.
Applications for Auto-Zero System solutions are assessed on case-by-case basis, subject to sample stream composition data and measurement specification requirements. Contact MCM’s Sales Application Team for more details.
For spot-check measurements in a hazardous area, MCM offers the ATEX MicroView Portable Hygrometer. The rapid sensor response, reduction of measurement hysteresis and in-built validation technology (via the Push Purge sensor-heating function) have made the ATEX MicroView Portable Hygrometer the preferred choice of plant technicians, who know to rely on its performance in processes where the accurate validation of process moisture conditions is critical to both the technical and commercial success of the project.
