Hydrogen Gas Detector

Hydrogen Gas Detectors (HGD) protect battery charging rooms and other locations where motive and stationary batteries are present by continuously monitoring hydrogen gas levels. The HGD is equipped with LED lights and an 80 dB alarm. AC- or DC-Powered models are available with a dual relay.

As a byproduct of the battery charging process, hydrogen gas accumulates in every battery room, and without robust ventilation systems, gas can accumulate to dangerous levels. Hydrogen mixes with oxygen to create a significant ignition hazard at a concentration of only four percent. Most safety measures recommend keeping hydrogen levels even lower, at less than one percent of the room's total volume. The gas is colorless, odorless, and lighter than air, so it is very difficult to track without sensitive monitoring equipment.

The Hydrogen Gas Detector Remote Display with Buzzer (HGD-RMT-BZR) is a small monitor box that duplicates the LED indicator lights, the audible warning buzzer, and the push-to-test button on the HGD.

The HGD-RMT-BZR can oversee as many as three detectors from a single station. The green LED indicates the HGD is powered up, the yellow LED lights up when 1% hydrogen is detected. The red LED lights and the warning buzzer comes on at 2% hydrogen.
