Ph meter calibration template
WebbpH Probes. In this experiment we will use a Ph probe, which is an electronic device that measures the pH. These are very common and they should always be checked against standard solutions of known pH and calibrated if they read incorrectly. The pH probe is an electrochemical cell and we will cover these in chapter 19, sections 19.3-19.5 and 19.7.
