WebIf not working according to any regulation, the principle is easy: For calibration, only those pH buffers are needed which bracket the pH range of your samples. For example, in a quality control where every sample should have a pH between 3.5 and 3.8, a two-point calibration with pH 2.00 and 4.01 is sufficient.
