October 16, 2013 – The HGD-2000 hydrogen gas detector by Eagle Eye Power is now available for DC power sources in addition to AC power. The DC-powered HGD-2000 gas detectors are commonly found in telecoms, in addition to utilities and other battery charging and storing rooms.

The HGD-2000 allows users to monitor hydrogen gas buildup in storage rooms and facilities that house batteries. Lead-acid batteries on charge emit hydrogen gas after reaching the 80% recharge point; when mixed with enough air, hydrogen becomes a highly flammable gas that can ignite easily with just a spark, destroying equipment and harming personnel. The lower explosive level (LEL) for hydrogen is 4.1% by volume. The dangers of hydrogen gas explosion are eliminated by using the HGD-2000 hydrogen gas detector. Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the yellow LED will light and the 1% internal relay will close. A 4-second delay prevents false activation. When the concentration reaches 2%, the red LED will flash, the internal 80db warning alarm will sound, and the 2% internal relay will close.
