Webba pH meter. Example 1: An electrode in pH 7.0 buffer generates +15 mV. When placed in pH 4.0 buffer it generates +175 mV. The net difference between the two buffers is +160 mV, which is then divided by +177.48 mV. The result, 0.901, is then multiplied by 100 to give a slope percentage of 90.1%. Example 2: An electrode in pH 7.0 buffer generated ... WebbIf 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. for the republic dress
