Application battery recharging areas
PolyGard EX sensors are used for monitoring battery recharging areas. The EX sensors are employed for detecting hydrogen concentrations in the air. This detonating hydrogen gas is produced during battery charging. MSR sensors protect persons and equipment against explosions caused by ignition of the hydrogen gas.
MSR offers sensors, controllers and accessories for battery recharging areas.
Some important details of the datasheets were pointed out here for a better overview.
