H2 SENSOR KIT-010-020

Environment H2 sensor kit

This H2-SENSOR Kit is a security system that constantly detects the amount of Hydrogen present in the working environment of the GC and blocks the Hydrogen generation if it detects an amount greater than the safety threshold.

The 6940.00.055 controller reads the percentage of Hydrogen measured by the sensor 6940.00.060 and, if the value exceeds the threshold alarm, the Controller deactivates the solenoid valve in the 6940.00.056 block.

The alarm can be signaled to a PC and to a remote device.
