Product Description


H2 Hydrogen Meter Single Gas Detector with 4-20mA RS485 Output
Hydrogen gas is lighter than air and is also a highly flammable gas. So customers usually need to detect its low explosion limit and detect the ppm or VOL concentration as well. They usually detect in battery warehouse,H2 gas cylinder houses or other experiments centers.

1. Monitor the H2 Hydrogen gas in environment or pipeline.
2. With self-calibration and zero calibration function, makes the detection more accurate and reliable.
3. Alarm mode is sound and light, alarm point is settable.
4. With temperature compensation, this is able to realize gas concentration compensation under conditions of different temperatures.
5. Infrared ray controller can remote control alarm point settings, zero calibration, and address modification. (optional)
6. Can output one or two on-off signals, can drive ventilator or solenoid valve and other external devices. (optional)
7. Working Voltage:24V DC
8. Case: die-cast aluminum
1. Standard equipped with three-wire system 4-20mA analog output; relay output; RS485 output.
2. Unique infrared ray control function, which can non-contacted control the device.
3. Being compatible with all kinds of controlled alarms, PLC, DCS and other control system, can be remote monitored.
4. Explosion-proof design, fast, reliable and stable.
5. Explosion-proof grade: Ex dⅡCT6
6. With self-calibration function, and three standard keys will be used to realize on-site maintenance.
7. Detachable probe/gas cell: It is very easy to calibrate and replace sensor
