Feature:
It is used to calibrate the accuracy of PH instrument. In order to ensure the measurement accuracy of the PH instrument, the detection results will shift with the prolongation of the experiment time, so the PH instrument should be calibrated regularly during the experiment.
Before and after each calibration of the PH instrument, the liquid on the electrode should be wiped with a paper towel before the next step of calibration, so as not to pollute the PH buffer, and the accuracy is more accurate. PH buffer cannot be reused.
