Multi-Parameter Self-Cleaning Water Quality Monitor All-Rounder for Household & Industrial Water Safety

Online water environment monitoring projects usually require simultaneous collection of multiple water quality indicators. Traditional solutions need multiple separate sensors with complicated wiring. Biofilms and suspended impurities growing in water easily stick to probes and lead to inaccurate readings. Operation and maintenance personnel must regularly visit sites for cleaning, consuming substantial manpower and resources. The multi-parameter self-cleaning water quality monitor integrates multiple monitoring capabilities and comes with an automatic cleaning function, which effectively addresses the challenges of long-term monitoring in complex water bodies.

The multi-parameter self-cleaning water quality monitor adopts an integrated compact design for simple installation and commissioning. A single unit supports synchronous detection of up to 8 parameters. Users can select digital sensors for dissolved oxygen, COD, pH, ORP, conductivity, ammonia nitrogen and turbidity as required, while collecting water temperature at the same time, suitable for most water quality monitoring scenarios. The device uses RS-485 bus and Modbus/RTU communication protocol for stable and reliable data transmission. It can be directly connected to the upper-level acquisition platform. Managers can track real-time water quality changes remotely and achieve 24/7 unattended monitoring.

The self-cleaning system is the core advantage of this monitor. Users can independently set the cleaning cycle and cleaning times to flexibly adapt to water bodies with different turbidity levels. The automatic cleaning device continuously cleans the surface of sensor probes to reduce microbial adhesion and sludge accumulation, prevent measurement drift caused by contaminants, effectively extend sensor service life and greatly cut on-site maintenance frequency. The sensor connectors adopt quick-plug waterproof structure. No complicated operations are needed for inspection and sensor replacement, improving on-site work efficiency.

The front end of the multi-parameter self-cleaning water quality monitor is equipped with a protective cover with diversion slots. It blocks large suspended particles and aquatic organisms from hitting the probe to protect sensors against physical damage, while ensuring normal water flow without interfering with water test results. All sensors deliver stable measurement performance. The accuracy of dissolved oxygen, turbidity, COD, ammonia nitrogen, pH, ORP, conductivity and temperature meets online monitoring specifications. Powered by 12VDC, the whole machine only consumes 5W with low energy consumption and stable operation. A 5-meter cable is standard, and custom lengths are available to fit different on-site installation distances.

This multi-parameter self-cleaning water quality monitor has a wide range of applications, applicable to municipal sewer network monitoring, inland river surface water monitoring, factory wastewater discharge supervision, aquaculture water quality control and other projects.
