How to do pH Electrode Calibration ?

Calibration Procedure – pH electrode  Select two buffers that bracket the expected sample pH. More buffers can be used for greater accuracy over a wider pH range. For best accuracy, use buffers that are no more than 3 pH units apart. Step by Step Procedure  1.Refer PH meter manual for specific details on operating your …
