Hydrogen gas detector WG-73.EG (selective), for garages serving fuel cell vehicles, 10/20/30% DGW, p-p sensor, power supply 230V

Gas Detector – Reliable Safety in Hydrogen Storage Areas

The WG-73.EG gas detector is an advanced device designed for continuous monitoring of hydrogen concentration in enclosed spaces. Particularly recommended for garages serving fuel-cell vehicles, where precise detection of leaks is critical for ensuring safety. The device utilizes a selective semiconductor sensor that ensures high measurement accuracy and minimizes the risk of false alarms. 230V power supply facilitates seamless integration with existing electrical infrastructure.

Functionality and Applications

The WG-73.EG detector not only alerts when hydrogen concentration exceeds permissible limits (10/20/30% DGW), but also activates visual alarm signaling and control outputs. This enables immediate activation of ventilation systems or shutdown of gas supply, significantly reducing potential hazards. The device performs reliably not only in garages but also in warehouses, vehicle inspection stations, and other facilities where hydrogen leakage risks exist.

Design and User Features

The detector is designed for easy installation and operation. Its single-piece, splash-proof housing (IP54 in recommended mounting position) ensures durability and resistance to environmental conditions. The replaceable gas sensor allows for quick and cost-effective replacement of the measuring element without requiring full device disassembly. Additionally, the detector is factory-standardized in the GAZEX Calibration Laboratory accredited according to PN-EN ISO/IEC 17025 (accreditation no. AP150), guaranteeing measurement accuracy and reliability. It features three alarm thresholds, and its isolated outputs enable flexible connection configurations — function selection is performed via a switch. All terminals are removable, simplifying the connection of multi-core cables.
