Discussion

Typically, a one-point calibration is made by placing the electrode in pH = 7.00 buffer and adjusting the meter to read 7.00. The procedure below outlines a one-point calibration.

1. Rinse the electrode with distilled water.
2. Place the electrode in a pH = 7.00 buffer solution.
3. Wait a moment for the meter to stabilize, and then adjust the meter until it reads a pH of 7.00.
4. Remove the electrode from the solution and rinse it with distilled water.
5. Replace the electrode in the pH = 7.00 buffer solution. If the reading does not return 7.00, then recalibrate the meter.

Narrative

Immerse the pH electrode into pH 7 buffer and turn the pH 7 potentiometer to adjust the read out on the meter to 7.00.
