PH Sensor Kits For Arduino With PH Electrode Probe BNC 0-14 Range, Fast Response ≤5S Plastic Shell Module For Water Quality Testing Projects(pH probe)

This Arduino pH sensor kit delivers solid performance for hobbyist water quality projects at an attractive price point. The BNC connector interface is industry-standard, simplifying integration with analog modules. Response time under 5 seconds handles most real-time monitoring applications adequately. However, the plastic shell housing feels cheap and prone to corrosion with extended submersion in harsh water conditions. Calibration requires patience—two-point calibration (pH 4.0 and 7.0 buffers) is essential but not included. The electrode itself performs reasonably well across the 0-14 range, though accuracy degrades slightly at extremes. Temperature compensation lacks automated adjustment, requiring manual offset calculations for precision work.
