CS1515D Digital pH Sensor

Short Description:

Digital pH Sensor is an online analytical device for continuous measurement of hydrogen ion activity (pH) in water. It features a rugged combination electrode with a low‑impedance glass membrane and an integrated reference electrode. The sensor directly outputs digital data via RS‑485 (Modbus RTU) with automatic temperature compensation (ATC) for accurate readings across a wide pH range (0–14). It is built with a durable, waterproof (IP68) body and features long‑term stability, fast response, and low maintenance. Typical applications include wastewater treatment, drinking water monitoring, industrial process control, aquaculture, and chemical processing. The digital design enables plug‑and‑play connectivity, remote calibration, and seamless integration into SCADA or IoT monitoring platforms. By providing continuous, reliable pH data, the sensor helps optimize chemical dosing (acid/alkali), ensure regulatory compliance, and maintain optimal conditions for biological and chemical processes. Unlike traditional analog pH sensors, the digital version eliminates signal interference and cable length limitations, making it an essential, cost‑effective tool for unattended, real‑time water quality monitoring.
