User's Manual Datasheet
Monitoring Gas Mixtures During Maintenance and Operation
Features
Suitable for use in ATEX, UKCA, IECEx, TR CU Ex & cQPSus certified Hazardous Areas
Monitors all three phases of hydrogen cooled electricity generators - normal running, purging and maintenance
Remotely change the measurement phase to match your maintenance schedule
Range indication via 4...20 mA output
Touch-screen display allows calibration or adjustment without the need for a hot works permit
Compact and rugged design with an EExd enclosure
IP66 rated enclosure
Low cost of ownership due to minimal maintenance
A multi-map binary gas analyzer designed specifically for the measurement of gas mixes present during the operation and maintenance of hydrogen cooled electricity generators. The primary measurement is hydrogen (H2) purity, with air as the background gas. The second measurement is monitoring hydrogen in carbon dioxide (CO2) during system purging, and finally carbon dioxide/air during maintenance. The analyzer is suitable for general purpose or hazardous areas and uses non-depleting sensor technology for minimal cost of ownership.
