Normally, pH measurements are made in water with 1,000 to 10,000 µS/cm conductivity. The conductivity comes from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the solution in ion form, which makes such solutions conducting. With 1,000 µS/cm conductivity of mobile ions pH electrodes have a good circuit and give fast, accurate pH readings.
