Fixed Real Time Monitoring Single Gas Detector 4-20mA Output H2 Hydrogen Sensor
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. With temperature compensation, this is able to realize gas concentration compensation under conditions of different temperatures.
4. Infrared ray controller can remote control alarm point settings, zero calibration, and address modification. (optional)
5. Can output one or two on-off signals, can drive ventilator or solenoid valve and other external devices. (optional)
6. Working Voltage:24V DC
7. Case: die-cast aluminum
