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.
Funtions:
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
Characteristics:
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
