Generic pH Electrode Probe for Liquid pH Value Detection - BNC Connector, 1m Cable

The probe is equipped with a standard BNC connector, making it directly compatible with most pH meters, controllers, and data loggers that feature a BNC input. For use with microcontrollers like Arduino, you will need a compatible pH sensor interface or signal conditioning module to read the electrode's analog potential.

The probe measures pH values from 0 to 14. It has a zero point of 7±0.5 pH and an alkali error of ≤0.2 pH, indicating good accuracy around neutral and alkaline ranges. The theoretical percentage slope is ≥98.5%, ensuring linear response across the scale.

For accurate readings, periodic calibration using standard pH buffer solutions (e.g., pH 4.01, 7.00, 10.01) is required. Always rinse the electrode with distilled water between measurements and store it in a recommended storage solution or pH 4 buffer to keep the glass membrane hydrated. Avoid letting the probe dry out.

The probe is rated for operation in solutions from 0°C to 60°C (with specifications also listing up to 80°C). Prolonged exposure to temperatures at the upper limit may accelerate aging of the electrode. Ensure the solution temperature is stable for most accurate measurements.
