The hydrogen gas detector protects battery charging rooms and other locations where motive and stationary batteries are present by monitoring hydrogen gas levels. Lead-acid batteries on charge emit hydrogen gas after reaching the 80% recharge point. Concentrations of 4% to 75% mixed with air can be explosive. Sparks or hot surfaces can ignite them. The hydrogen gas detector will provide a warning and facilitate dissipation of the hydrogen, by operating alarms and exhaust fans before it reaches the lower explosive limit of 4%.

In addition to protecting your property and employees, cost savings are also realized. Insurance premiums may be reduced as a result of a hydrogen gas detector installation. Electricity costs decrease as a result of controlled exhaust fan operation rather than continuous fan operation. Air conditioning and heating costs are also reduced as a result of the controlled fan operation.

Two models are available: AC or DC, Optional accessories include steel junction box for mounting on wall or ceiling, remote panel for eye level placement, and modular cable for connecting the remote to the detector.
