Lead-acid storage batteries emit hydrogen while gassing during charge. Hydrogen concentration of 4% to 75% by volume in air are potentially explosive. Hydrogen gas detector is designed to provide for dissipation and warning before any concentration reaches the lower explosive limit (LEL) of 4%.
- 1% Concentration energizes a relay which activates your exhaust fan
- 2% Concentration activates a built-in, pulsating warning alarm
