  • Page 28: Standardization

    STANDARDIZATION 6.1 Using Setup Conductivity probes are generally identified as having characteristic cell constant, 0.1, 1.0 or 10.0 which reflects their physical geometry and their range of application. However, these are typically nominal cell constants. The actual cell may vary somewhat from the nominal values, and therefore the actual cell constant must be calculated using a solution with a known conductivity value.

  • Page 30 Resistivity/ TDS Standardization Follow the same procedure as explained in the conductivity calibration. Note: There are separate standardization provided for conductivity, TDS and resistivity. And also in each mode there are separate calibration for 2 cell and 4 cell. So altogether 6 independent calibration are available and each acts independently.

  • Page 36: Conductivity Operation

    CONDUCTIVITY OPERATION 8.1 Replatinization Replatinization is the process of replacing the replacing the platinum on the surfaces of the 2-cell conductivity probes that may flake or wear off over time. The platinum on the surface of the probe is used to increase the measuring surface area, resulting in decreased population error.

  • Page 37: Conductivity Theory

    CONDUCTIVITY THEORY Conductance is a metric associated with the ability o primarily aqueous solutions to carry an electrical current, I, between two metallic electrodes when a voltage E is connected to them. Though water itself is a rather poor conductor of electricity, the presence of ions in the water increases its conductance...
  • Page 38 (µS/ cm) or milli-Siemens per cm (mS/ cm). The accumet Basic AB30 meter automatically converts conductivity readings from micro or milli Siemens to other derived units that are widely used. These are ppm TDS (total dissolved solids), and Resistivity (ohm*cm).
  • Page 39 Conductivity Measurement Accumet conductivity probes consist of glass or epoxy bodies in which platinum or platinised sensing elements and are designated two-cell electrode has two such sensing elements and are designated two-cell electrodes. The previous discussion has focused on this type of electrode. Four cell electrodes are also available, and the theory and application of these are in a separate section.
  • Page 40 The four-cell electrode Traditionally, conductivity measurements were made with a Òtwo cellÓ electrode. This electrode used two metallic sensors, an anode and a cathode to which ions migrated. Under the influence of DC current the electrodes quickly became polarized. In this situation, molecules formed at the electrode surfaces and ions migrating to the area collect around the respective anode or cathode and actually screen it from other ions.
