CS6712D Digital Potassium Ion Sensor

Short Description:

Digital Potassium Ion Sensor is an online analytical device for continuous measurement of potassium ion (K⁺) concentration in water, wastewater, and other aqueous solutions. It operates on the principle of ion‑selective electrode (ISE), typically using a valinomycin‑based polymer membrane, which provides exceptional selectivity for potassium over other cations such as sodium (Na⁺) and calcium (Ca²⁺). The sensor integrates a reference electrode and automatic temperature compensation (ATC), delivering accurate, drift‑free readings over a wide range (e.g., 0–1000 mg/L). It directly outputs digital data via RS‑485 (Modbus RTU), enabling plug‑and‑play integration into SCADA or IoT platforms. Its robust, waterproof (IP68) housing and low‑maintenance design make it suitable for demanding applications such as drinking water monitoring, wastewater treatment, aquaculture, agricultural runoff control, and industrial process control. Unlike colorimetric or flame photometry methods, the ISE‑based sensor requires no reagents, no sample preparation, and provides real‑time data. By delivering continuous, reliable potassium readings, it helps optimize nutrient management (e.g., in hydroponics or fertilizer dosing), monitor water quality in rivers and lakes, and ensure compliance with environmental discharge limits. The digital output eliminates signal interference, supports remote calibration and self‑diagnostics, and reduces operational and maintenance costs, making it an essential tool for unattended, continuous water quality monitoring.
