Care is needed in the selection and installation of sensors for obtaining reliable pH measurements in high purity water samples.
Power plant cycle chemistry guidelines and standards specify narrow ranges of pH to minimise corrosion of highly valuable components. In addition, makeup water treatment systems using two-pass reverse osmosis optimise performance by careful control of pH between passes. In both of these applications, pH must be measured accurately under the difficult conditions of low conductivity.
