Description:

Digital hardness sensor, developed based on ion selection method, is an electrochemical sensor based on sensitive membrane. This membrane is a component that makes the electrode selectively respond to specific ions. It is made of industrial-grade PVC membrane hardness ion selective electrode, which selectively tests the hardness ion content in water; fast response speed and accurate measurement; built-in temperature sensor, automatic temperature compensation, suitable for online long-term monitoring environment; digital sensor, direct output RS485 digital signal, support MODBUS protocol;

Features:

On-site plug and play
Low power design
Internal circuit anti-interference design
Integrated automatic temperature compensation
Waterproof grade IP68
Internally stores calibration data
Supports offline calibration
RS485 digital interface, standard Modbus communication protocol
