Online pH Water Quality Monitor
Model：ERUN-SZ2-B-B7A
Parameter: pH
Water pH online sensor adopts long-life industrial online electrode, built-in temperature sensor automatic temperature compensation, suitable for long-term online monitoring use. The sensor adopts RS485 digital output and supports Modbus protocol, which is convenient for networking and system integration without controller. Widely used in water quality treatment, hydrological monitoring, wastewater treatment swimming pools, industrial control, biology and other fields of water quality pH for continuous real-time monitoring.
