Liquid pH Sensor With BNC pH Electrode Probe For Arduino

The Liquid pH Sensor with BNC pH Electrode Probe is a high-precision tool for measuring the pH of aqueous solutions, helping determine whether they are acidic, neutral, or alkaline. With a wide detection range of pH 0–14 and high accuracy of ±0.1 pH at 25°C, it is ideal for Arduino projects, environmental monitoring, chemistry experiments, and water quality testing. Combining a pH glass electrode and a reference electrode, it delivers fast and reliable readings with a proportional analog voltage output for easy microcontroller integration.
