Product Overview
The SX-CCFMA 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. The probe includes a built-in temperature sensor, and automatic temperature compensation helps maintain measurement accuracy across varying temperatures.
