The GEC-EC485 is a new generation intelligent digital conductivity sensor independently developed by GAIMC, which can realize direct measurement without a host. It can detect conductivity (TDS) and temperature values in solutions in real time, and output 4-20mA analog signals to back-end equipment.
Equipped with RS485 interface, it can connect to computers through MODBUS protocol to realize remote data monitoring and recording. With high precision, good stability, long service life, fast response and low maintenance cost, it is widely used in continuous water quality monitoring of thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, food and tap water industries.


EC/TDS measurement accuracy up to ±2%F.S, temperature accuracy ±0.3℃ for reliable data.
0~20ms/cm standard range, customizable to 300ms/cm for various industrial scenarios.
Direct output 4-20mA analog signal and RS485 digital signal, flexible connection with equipment.
Real-time temperature compensation ensures measurement accuracy at 0~60℃ working temperature.
High-grade waterproof and dustproof, suitable for harsh industrial on-site water immersion environment.
Power failure protection function for more than 10 years, no loss of configuration parameters.
