SPS-pH Water Quality Sensor

pH Water Quality Sensor

The pH Water Quality Sensor uses a composite electrode combining a glass indicator electrode and a reference electrode to measure the hydrogen ion concentration (pH) of water. The potential of the internal reference electrode remains stable regardless of the solution’s pH. When the glass bulb is immersed in water with varying H⁺ concentrations, a potential difference forms between the indicator and reference electrodes. This difference is detected by the voltmeter and converted into the pH measurement result.

The sensor supports RS485 output (Modbus RTU communication) and features a compact, integrated controller module with the pH electrode for easy installation and reliable performance.

The pH sensor is suitable for a wide range of applications, providing accurate and stable monitoring in various water conditions.

Applications:

• Urban and industrial sewage treatment monitoring
• Seawater, fishery, and aquaculture water quality control
• Surface water assessment
• Drinking water and pipeline network monitoring
