Product Overview
The SX-CCFNA Series online conductivity/salinity sensor uses advanced four-electrode measurement technology with an RS-485 digital interface and Modbus protocol support. Compared with traditional twoelectrode sensors, it provides higher accuracy, a wider measurement range, and improved stability. It is widely used in surface water, municipal wastewater, industrial wastewater, wastewater treatment, industrial process water, and aquaculture.
Main Features
- RS-485 communication interface, standard Modbus protocol, for easy integration
- Simultaneous output of conductivity, salinity, TDS, and temperature
- Corrosion-resistant housing, IP68 waterproof rating, suitable for long-term submersible operation
- Built-in temperature sensor with automatic temperature compensation
- Built-in calibration parameters, factory-calibrated for quick installation and commissioning
