Online pH sensor
Key specifications:
✅Range 0-14
✅RS485,MODBUS protocol
✅Glass electrode method
✅Easy on-site use
✅Online real-time monitoring
The pH sensor consists of a glass electrode and a reference electrode, in which the glass electrode has special electrochemical characteristics and measures pH by sensing the concentration of hydrogen ions in the solution. Built-in temperature sensor with automatic temperature compensation, suitable for long-term online monitoring environment, support a variety of terminal networks, widely used in water quality treatment, hydrological monitoring, wastewater treatment, aquaculture, swimming pools, industrial control, biology and other fields.
