Digital conductivity sensor series CS3742D

Short Description:

Digital Conductivity Sensor: Digital Conductivity Sensor is an online instrument for continuous measurement of electrical conductivity in liquids, directly indicating total ionic concentration (salinity, TDS). It operates on a two‑ or four‑electrode design (graphite or platinum) with an alternating current to prevent polarization. The sensor features a built‑in temperature sensor for automatic temperature compensation (ATC) and directly outputs calibrated readings in μS/cm or mS/cm via RS‑485 (Modbus RTU). Its digital output eliminates signal errors and supports plug‑and‑play connectivity, remote calibration, and self‑diagnostics. With a wide measurement range (0‑2000 μS/cm to 0‑2000 mS/cm) and rugged, waterproof (IP68) housing, it suits water treatment, reverse osmosis, cooling towers, aquaculture, and industrial process control. Real‑time, continuous data helps optimize chemical dosing, protect equipment from scaling or corrosion, ensure product quality, and maintain regulatory compliance. Compared to analog sensors, the digital version simplifies system integration, reduces maintenance, and provides reliable data for unattended water quality monitoring. It requires no reagents or sample preparation, making it an essential, cost‑effective tool for environmental and industrial applications.
