The Eagle Eye HGD-2000 Hydrogen Gas Detector allows the user to monitor hydrogen gas buildup in storage rooms and facilities that house batteries - including forklifts, golf carts, backup power supplies, and battery charging stations. 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.
The HGD-2000 fixed hydrogen gas detector is easy-to-use and easy-to-install. Attach the HGD-2000 to the wall, ceiling, or optional junction box using the mounting holes at the top and bottom of the detector box. The detector has a terminal block for connection to single-phase AC power source and two internal relays. The relays can be used to switch a remote exhaust fan and/or alarm on and off. The detector should be kept on at all times, and the green LED will be lit. If the concentration of hydrogen gas in the air surrounding the sensor reaches 1% by volume, the yellow LED will light and the 1% internal relay will close. A four second delay prevents false activation. If the concentration reaches 2%, the red LED will flash, the internal 80 db warning alarm will sound, and the 2% internal relay will close.
