Conductivity sensor

Ultra‑Precision Conductivity Sensor – Essential for Accurate Liquid Analysis

The conductive sensor employs a dual‑electrode assembly to measure the electrical conductivity of aqueous solutions with high fidelity. By delivering a low‑power AC excitation and detecting the resultant impedance across the electrodes, the sensor resolves ionic concentrations in the range of 0.01 µS/cm to 10 mS/cm. Integrated temperature compensation and a stable reference electrode ensure traceability to CIPM standards, making the unit suitable for critical process monitoring, laboratory validation, and environmental compliance.

Designed for rugged deployment, the sensor features a sealed probe with corrosion‑resistant titanium or stainless‑steel electrodes, a built‑in temperature sensor, and optional optical cable for remote operation. The compact PCB hosts an analog‑to‑digital converter and a low‑noise amplifier, producing a 24‑bit reading that is output via multiple industrial interfaces, allowing easy integration into PLCs, SCADA systems, or data acquisition platforms.
