Get A QuoteThe FST100-EC106 EC Sensor is an intelligent electrical conductivity (EC) sensor engineered for precise conductivity measurement in a wide range of water quality monitoring applications. It supports industry-standard RS485 (Modbus RTU) communication, allowing seamless integration with PLCs, DCS systems, industrial computers, data loggers, and other automation equipment.
Designed with dual high-impedance differential amplifiers, the sensor delivers excellent anti-interference performance and rapid response even in electrically noisy industrial environments. Its automatic Pt1000 temperature compensation ensures consistent measurement accuracy across varying water temperatures.
The rugged stainless steel construction and IP68 protection rating make the sensor suitable for long-term submerged operation in pipelines, tanks, reservoirs, and open water environments. The 3/4" NPT threaded connection simplifies installation while supporting both immersion and inline mounting configurations. The FST100-EC106 is widely used in wastewater treatment, industrial process monitoring, environmental water quality assessment, aquaculture, cooling water systems, and chemical processing.
