Hydrogen Gas Detector

Hydrogen gas detectors are hydrogen gas monitors that act as hydrogen gas alarms and exhaust fan controllers.

Operation:

Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume, the "1% Caution" yellow LED will light and the 1% internal relay will close. Should the hydrogen gas concentration reach 2% by volume, the "2% Warning" red LED will flash and an 80 db alarm will sound; the 1% relay will remain closed and, if a Dual-Relay model, the 2% internal relay will close. Either relay can activate a remote exhaust fan and/or alarm.
