Online Conductivity (Salinity) Water Quality Monitor
Model：ERUN-SZ2-B-A4
Parameter: Conductivity (salinity)
Adopting the international leading four-electrode technology, RS485 digital interface, support MODBUS protocol. Compared with the traditional two-electrode sensor, it not only has higher precision, but also has a wider measuring range and better stability. Widely used in surface water, municipal sewage, industrial wastewater, sewage treatment, industrial processes and aquaculture water quality conductivity for continuous real-time monitoring.
