What are the maximum temperature and pressure tolerances of the pH meter? What types of pollution and corrosion are most harmful to electrodes?
What is encountered is at normal temperature and pressure, with an alkalinity greater than 14; especially liquid alkali cannot be used for long periods of time, while soda ash is more suitable. It cannot tolerate strong solvents, especially those with plastic casings.
pH meters cannot withstand high pressures; the operating pressure should not exceed 1.0 MPa. It is best to use them at room temperature, as higher temperatures can cause corrosion of the glass electrode
