The SN-3003-EC-N01 Four Electrodes EC Sensor is a high-precision four-electrode EC (electrical conductivity) sensor designed for reliable, long-term monitoring of water quality. With a wide conductivity range of 1–200,000 μS/cm and salinity support up to 70 PSU, it delivers stable, anti-polarization measurements even in high-conductivity environments. The sensor’s compact, integrated design makes it easy to install and maintain.

Its IP68 waterproof rating ensures dependable operation in submerged applications. Supporting ModBus-RTU over RS485, it can be easily connected to data loggers, computers, or PLC systems. Temperature compensation and customizable ModBus address and baud rate enhance usability. With DC 10–30V wide-voltage input, this sensor suits a variety of environmental, industrial, and aquaculture applications where accurate EC data is crucial.
