Why a four-electrode design for online conductivity monitoring?

The four-electrode graphite configuration avoids polarization and resists fouling, so accuracy holds over long unattended deployments in complex water — where two-electrode sensors drift.

Does the IDC report TDS and salinity directly?

The sensor measures conductivity with automatic temperature compensation across 0–200 mS/cm; TDS and salinity conversions are handled by the connected TENGINE controller.

Tổng quan

A conductivity sensor measures the ability of water to conduct electrical current, which correlates directly with dissolved ion concentration — the basis for TDS, salinity and concentration monitoring.

The IDC Integrated Digital Conductivity Sensor adopts a four-electrode graphite configuration. An AC signal is applied to two electrodes to avoid polarization interference, while the other two electrodes are used for precise conductivity measurement. Compared to traditional two-electrode technology, it offers greater measurement stability and improved resistance to fouling, making it ideal for long-term online monitoring in complex water environments.
