EmailThe ZPH-02 pH Sensor is a kind of intelligent pH electrode adopting RS485 communication interface and standard Modbus protocol. It can be widely applied to pH monitoring in sewage plants, waterworks, surface water and aquaculture, etc.
Features
With corrosion resistant shell and IP68, applicable to all kinds of poor working conditions
Adopt industrial-grade combination electrode and double salt bridge design of reference electrode, the service life is long.
With built-in PT1000 temperature sensor and compensation algorithm, the accuracy can reach ±0.1℃.
Use RS485 communication interface and standard Modbus protocol, convenient for integration
