The CC 603-1 Conductivity Controller and Transmitter provides accurate monitoring, control, and transmission of conductivity values using 4–20mA and RS-485 MODBUS RTU communication. Conductivity measurement reflects the concentration of conductive ions such as chlorides, carbonates, and dissolved solids in water. Designed for industrial conductivity sensors and temperature compensation, this controller is ideal for water treatment, chemical processing, food industries, textile applications, and neutralization processes.
