DCD Digital Conductivity Meter

Water supply to the water plant

Surface water monitoring

Seawater conductivity or salinity measurement

Influent from sewage treatment plant

● Digital sensor, obviously improve the anti-interference ability of the sensor. Increasing the sensor cable to hundreds of meters in length can still ensure high-precision measurements;

● Sensor plug and play, the system automatically recognizes and supports multi-channel measurement;

● Multi-frequency measurement, digital filtering technology can adapt to the application of different occasions;

● Automatic range switching;

● The transmitter can provide isolated RS232 / RS485 digital interface and support communication protocols such as MODBUS;

● Programmable relay output: Any relay can be set to high alarm, low alarm, timer mode;

● It has the function of automatic saving of historical data, which can store historical data information for 10 years.
