Core Advantages
24/7 Continuous Monitoring & Proactive Early Warning
Deployed along water supply pipe networks and decentralized water supply points, the system delivers round-the-clock continuous monitoring and instant abnormal alerts, enabling early risk identification rather than passive post-event data review.
Multi-Technology Integrated Design
Integrated optical, electrochemical and physical sensors support synchronous multi-parameter detection of residual chlorine, turbidity, pH and more. It avoids data desynchronization caused by assembling multiple single-parameter meters.
Automatic Cleaning & Defoaming for Maintenance-Free Operation
Equipped with electrode reverse polarization cleaning, wiper-based turbidity cleaning, flow flushing and automatic defoaming functions. Effectively prevents data drift and measurement deviation, ensuring long-term stable operation without frequent manual maintenance.
Powerful Network Compatibility for Government Platform Access
Supports Modbus-RTU and RS485 for SCADA and PLC system docking. The GHFA-200 model adopts the standard HJ212-2017 protocol with customizable interfaces, enabling direct data upload to official environmental and water resource supervision platforms, fully meeting governmental project compliance requirements.
Flexible Deployment for All Scenarios
Dual deployment solutions cover diverse site conditions. The compact GHFA-220 all-in-one unit features low power consumption (20W) and 12–24VDC power supply, compatible with solar power for off-grid decentralized sites. The GHFA-200 station supports mains power and large-screen touch display for standardized station-level projects. Relay and 4-20mA output linkage support local alarm and automatic dosing control.
