We use the following methods to calibrate the pH
- Rinse the electrode with the deionized water and blot dry using a piece of tissue (Shur Wipes or Kim wipes are available in the labs).
- Place the electrode in the solution of pH 7 buffer.
- Allow the display to stabilize and then set the display to read 7.
- Follow the above steps 3-4 times to check the accuracy.
