The hydrogen alarm (NDR-H2-1A) detects leaked gas and alerts the surrounding area of the danger of gas leakage. A buzzer and LED lamp alarm will be activated when the threshold is 500ppm. The power supply is AC100V, and an A contact relay is provided as an external output. It can be used in a variety of ways, from simple installation to interlocking devices. Application examples: gas chromatography, hydrogen cutting, hydrogen generators, near hydrogen cylinders, etc.
- Measurement range
- 500 to 20,000ppm (range error 15%)
- Detection target gas
- hydrogen
