Binary Gas Analyzer for Hydrogen Cooled Generators

Monitoring Gas Mixtures During Maintenance and Operation

Features

Suitable for use in ATEX, IECEx, TC TR Ex & cCSAus 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
