AG-GDC-150 Flammable Gas Detectors
Fixed Hydrogen Detector
Catalytic bead hydrogen detection for battery rooms and electrolyser areas
4–20 mA Modbus RTU
Features
- Hydrogen is the lightest gas — mount at the highest point of the room and in every roof pocket
- Standby batteries vent hydrogen on charge; detection is normally interlocked to the room ventilation
- Two field-adjustable alarm stages drive ventilation boost and charger shutdown independently
- Catalytic sensors require scheduled bump testing and calibration to remain reliable
