Core Highlights
- Multiple installation methods adaptation: The host adopts wall mounted installation (four fixed holes, center hole distance of 125/149/183.5mm optional), with electrode support for immersion, insertion, and flow installation, flexibly adapting to different on-site environments such as water tanks and pipelines.
- High precision stable monitoring: built-in bubble elimination system to reduce the interference of bubbles on measurement; Low turbidity 0.01NTU, high turbidity 0.1NTU, high resolution, ± 5% FS measurement accuracy, good data repeatability.
- Industrial grade anti-interference design: using dedicated signal transmission lines, with strong anti-interference ability, suitable for complex electromagnetic environments in industrial sites, ensuring continuous and stable operation.
- 4–20m of rich output and controlThere are two sets of programmable relays, an analog output, and an RS485 digital connection. You can create alarm or timer functions to satisfy the needs of industrial automation.
Featured Applications
- Industrial manufacturing: turbidity control in the preparation process of electronic semiconductor ultrapure water, monitoring of suspended solids in food and beverage production water, and water quality control in printing and dyeing wastewater treatment processes;
- Environmental protection engineering: monitoring of effluent from garbage leachate treatment stations, compliance testing of water quality in centralized sewage treatment plants in chemical industrial parks, and tracking of turbidity during the clarification process of mine wastewater;
- Other scenarios: monitoring of water quality in aquaculture ponds, monitoring of discharge after hospital sewage treatment, and screening of turbidity in agricultural irrigation water.

Daily maintenance and precautions
Installation and operation points
- The host is mounted on the wall using M3 bolts, avoiding high temperatures, humidity, corrosive conditions, and direct sunlight. Waterproof sealing should be done before electrode placement. The base should be welded to the pipeline for plug-in installation and a flow cup for flow type.
- Specifications for wiring: Sensor red wire to V+, yellow to V-, blue to INA, green to INB; 4-20mRS485 communication A is connected to terminal A. T, and B is connected to terminal B. R; connect the AC220V power supply L terminal to the corresponding terminal, the N terminal to the neutral wire, and the PG terminal to ground.
- Method of operation: View real-time data of numerous settings on the LCD widescreen after booting; Standard solution calibration or on-site comparison can be used. Follow menu prompts to set relay trigger value and action mode to meet monitoring needs.
Daily maintenance and troubleshooting
- Thoughts on maintenance: To keep things clean, clear the input and exit pipes, as well as the electrode light window and flow cell. If the measurement mistake is big, you should calibrate quickly. Some connections keep interference from happening.
- RS485 connection doesn’t work? Check the wiring one more time, and make sure the power source works with the parameters for communication. When electrodes are dirty, they raise the turbidity level too much. If something leaks, check the waterproof seal and keep the water flow at the recommended level.
