Designed to meet the US Department of Defense (DoD)’s rigorous UFC 3-520-05 requirements, the SBS-H2-DoD Hydrogen Detector is an upgrade of our popular SBS-H2 system, providing improved Lower Explosive Limit (LEL) detection levels. It is currently used by the Army, Navy and NASA.
Traditional detectors are designed to measure the amount of hydrogen gas in the air and provide warnings when gas levels reach 25 percent and 50 percent of the LEL concentration. The SBS-H2-DoD detects hydrogen at 12.5 percent and 25 percent of the LEL – a significant additional safety margin that is critical for military applications. The detector’s lower alert levels equal more time to address the issue creating the hydrogen gas, and more time means increased overall safety.
The SBS-H2-DoD has visual and audible alarms and 0.5% and 1% hydrogen relays. The device features CAT cable connections between the main unit and up to three sensors, leading to easier installs and retrofits into sensitive and classified environments. Each sensor monitors up to 600 square feet of space and can be powered by AC and/or DC power.
The system comes complete with the main control, a highly accurate hydrogen gas sensor and a 25 ft. cable. This unit can be powered with AC and/or DC power and can be mounted directly to a wall or to an electrical box, making it extremely versatile and very user-friendly.
The SBS-H2-DoD includes relays for remote connection to alarm/monitoring systems and for control of external relays for an exhaust fan.

Warning Settings: Should the concentration of hydrogen gas in the air surrounding the sensor reach 0.5% by volume, the “0.5% Warning” yellow LED will light up on the main control of the unit. In addition, the 0.5% internal relay will energize and can be used to activate an external exhaust fan or a building management/alarm system (via SCADA Modbus).
Alarm Settings: Should the hydrogen gas concentration reach 1% by volume, the “1% Alarm” red LED will light up, the strobe will flash and an audible alarm will sound. In addition, the 1% internal relay will energize and can be used to activate a building management/alarm system (via SCADA/Modbus).
