The S-pH003 online pH sensor adopts the electrochemical principle, and realizes pH measurement through a linear system composed of a measurement electrode (sensitive to pH changes in the medium) and a reference electrode.
Equipped with an industrial-grade electrode core, this sensor supports various types of pH probes, such as those for ultrapure water, high-temperature, low-temperature, desulfurization & denitrification, and hydrofluoric acid resistance.
It features temperature compensation, enabling functions like temperature compensation and digital signal conversion. With RS485 output and the standard MODBUS RTU protocol, it supports networking with various terminal devices.
Key Features
- Dual salt bridge online industrial electrode, strong anti-contamination capability;
- Built-in temperature sensor, real-time temperature compensation;
- IP68 waterproof rating, suitable for various working conditions.
