This professional self-cleaning RS485/Modbus multi-parameter water quality sensor features an integrated industrial-grade design. It supports simultaneous measurement of 8 water quality parameters (e.g., DO, COD, pH) with customizable configurations. Equipped with an automatic cleaning system, it effectively prevents microbial adhesion and cuts maintenance costs significantly. Adopting RS485 bus and Modbus/RTU protocol, it transmits data directly to collection platforms. With IP68 waterproof rating, POM+316L materials and easy submersible installation, it enables long-term accurate online monitoring for various water quality scenarios.
This product is suitable for drinking water, various water supply systems and recirculating aquaculture water. It adopts RS-485 (Modbus RTU protocol) signal output, which can be easily connected with PLC, DCS, industrial control computers, general controllers, paperless recorders, touch screens and other third-party equipment. It adopts 3/4 NPT thread design for submerged installation, which is convenient for installation in pipelines, water tanks and other occasions, with IP68 protection level, and can output conductivity and TDS at the same time.
This product is specially designed for the continuous online monitoring of residual chlorine in aqueous solutions. It is widely applied in drinking water treatment plants, canning factories, water distribution networks, swimming pools, cooling circulating water systems, and various water treatment projects, ensuring stable and reliable water quality detection.
The ZW-TB-PR integrated online turbidity sensor adopts the scattered light detection principle. During operation, a incident light beam penetrates the water sample. Turbidity particles within the sample scatter the light beam. The sensor measures the intensity of light scattered at 90 degrees to the incident path. By correlating the measured data with the built-in calibration standard, the system derives the true turbidity value. Post-processing includes linearization algorithm implementation, ensuring the final output is accurate, stable, and ready for system integration.
ZW-NHN-PRA is an integrated online ammonia nitrogen sensor based on a PVC membrane ammonium ion-selective electrode. It features real-time temperature compensation for fast, simple, accurate and cost-effective measurement of ammonium ions in water. The sensor supports RS‑485 and Modbus/RTU for easy integration with PLC, DCS, industrial controllers and other third‑party devices. Its patented ion probe with a slow‑leak reference system ensures high stability and extended electrode life. With 3/4 NPT threads and IP68 protection, the sensor enables easy installation in submerged, pipeline or tank environments.
