H2 Sensor

The VICI DBS H2 - Sensor provides a real-time bar graph display of the concentration of hydrogen in the GC oven. If there is leakage to the threshold level, an audible alarm sounds and the display flashes.  If the leak continues until the upper limit of hydrogen concentration is reached, the system will stop the VICI DBS hydrogen generator. An optional feature is a valve which will activate an inert gas purge of the GC oven when the upper limit of hydrogen is reached.  When normal levels are restored, operations can be restarted.

The following option is available:
• Purge gas valve
