Measuring principle pH measurement

The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The membrane glass of the electrode supplies an electrochemical potential which is dependent upon the pH value of the medium. This potential is generated by the selective penetration of H + ions through the outer layer of the membrane. An electrochemical boundary layer with an electric potential forms at this point. An integrated Ag/AgCl reference system serves as reference electrode.

The transmitter converts the measured voltage into the corresponding pH value using the Nernst equation.

Important properties

Reference system: The CPF 201 electrode has a porous Teflon reference junction in a double reference chamber for long life in all high purity water applications.

Temperature compensation: In addition, a Pt 100 or Pt 1000 temperature sensor is embedded in the pH glass bulb stem for quick temperature response.

Easy connection: The electrode is connected via the water-proof plug-in system TOP 68.

Flow assembly: The flow cell has been designed to dissipate static electrical charges inherent in flowing water with low conductivity. The flow assembly design minimizes trapped particles and contaminants.

Measuring system

The complete measuring system comprises:

  • PuriSys CPF 201 electrode with stainless steel body
  • PuriSys CPF 201 stainless steel flow assembly with compression fitting on inlet and outlet
  • CPK 9 measuring cable (not included in scope of delivery)
