Characteristics & Functions
1. Being compatible with all kinds of controlled alarms, PLC, DCS and other control system, can be remote monitored.
2. Explosion-proof design, fast, reliable and stable. Explosion-proof grade: Ex dⅡCT6
3. With self-calibration function, and three standard keys will be used to realize on-site maintenance.
4. Monitor the PH3 concentration in environment or pipeline and alarm.
5. Two-stage alarm with sound and light, alarm point is settable.
6. Infrared ray controller can remote control alarm point settings, zero calibration, and address modification.
7. Can output one or two on-off signals, can drive ventilator or solenoid valve and other external devices.
