What is pH Measurement via Direct Potentiometry about?

The document describes the procedure for determining the pH of a sample using direct potentiometry with a glass electrode sensitive to protons. It explains that the electrode measures the electric potential when immersed in a sample, and that it is calibrated using standard solutions of known pH in order to then calculate the pH of the sample. It also highlights some limitations and errors such as variations in ionic strength or blockage of the salt bridge.
