LGS-05 Water Supply Multi-Parameter Analyzer embodies the design philosophy of reliable data and minimal maintenance, redefining safety and efficiency in decentralized water supply. It integrates comprehensive capabilities—including water quality monitoring, automatic cleaning, fault diagnostics, and data transmission—while its intelligent data quality control system ensures data integrity and authenticity. By significantly reducing on-site operational burdens, the analyzer provides robust support for the fine-grained management of drinking water safety across the entire chain, from source to tap.
· High-Precision Measurement
· Long-Term Maintenance-Free Operation
· Simplified On-Site Maintenance
· Intelligent Data Verification
Core Functions
· Online Monitoring & Calibration
Equipped with pH, turbidity, and residual chlorine sensors (expandable),the analyzer supports on-site calibration and measurement mode switching.
· Fully Automatic Flow Control
Features a low-turbulence, anti-bubble flow cell and a dual self-cleaning mechanisms combined with drainage and air-purging. The system monitors liquid levels, inlet flow rates, and pump/valve status in real-time to automate sampling, drainage, and pipeline flushing.
· Intelligent Data QC & Storage
The system performs automatically grades data quality (Good / Suspicious / Faulty) to eliminate false readings. It supports local historical data storage, offline caching, breakpoint resume transmission upon reconnection, and built-in high-precision clock synchronization.
· Comprehensive Fault Self-Diagnosis & Alarms
The analyzer integrates 59 built-in anomaly detection models to accurately identify faults such as water shortages, sensor aging, pipeline blockages, and communication failures.
· HMI (Human-Machine Interface)
The 7-inch color capacitive touchscreen features a human-presence sensor for automatic wake-up and enters sleep mode when idle. With a guided calibration interface, users can easily access real-time water quality data, historical trend curves, and alarm logs.
· Remote O&M & Expansion
The system supports remote parameter configuration, instant measurement commands, and OTA firmware upgrades. Reserved expansion interfaces adapt to various retrofit scenarios.
