Hydrogen Gas Detector

Lead–acid storage batteries emit hydrogen while gassing during charge. Hydrogen concentration of 4% to 75% by volume in air, is potentially explosive. The HGDI-DR hydrogen gas detector is designed to provide dissipation and warning before any concentration reaches the lower explosive limit (LEL) of 4%.

Benefits

â–  Protects against battery charging room explosions â–  Inexpensive protection for your property and employees â–  Decreases electricity costs as a result of controlled exhaust fan operation â–  Reliable, uninterrupted 24/7 monitoring and control â–  Both relays are SPDT (form C) and both sets of contacts are available to the user â–  Relay 2 can be configured to be energized on start-up
