CS1797D Digital pH Sensor
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 sensing bulb and an integral reference electrode. The sensor directly outputs digital data via RS‑485 (Modbus RTU) with automatic temperature compensation (ATC), delivering accurate readings over the full 0–14 pH range. Its durable, waterproof (IP68) housing and low‑maintenance design are suitable for demanding environments such as wastewater treatment, industrial process control, aquaculture, and drinking water monitoring. Unlike analog pH sensors, the digital version eliminates signal interference, supports remote calibration and self‑diagnostics, and enables plug‑and‑play connectivity without cable length restrictions. By providing continuous, real‑time pH data, it helps optimize chemical dosing (acid/alkali), ensure regulatory compliance, and maintain optimal conditions for biological and chemical processes. The digital pH sensor is an essential tool for unattended, continuous water quality monitoring, offering long‑term stability, fast response, and reduced operational and maintenance costs. Its output can be directly integrated into SCADA or IoT platforms, making it ideal for both municipal and industrial applications. -
