Conductivity Sensing Wildcard

Conductivity sensing I/O board precisely measures aqueous liquid conductances/conductivities.

Conductivity cell transmitter

The Conductivity Sensing Wildcard can be used to measure either solution conductivity or total ion concentration of aqueous samples for analytical investigation or process measurement. The Conductivity Sensing Wildcard measures the ability of a solution to conduct an electric current between two electrodes. In solution, the current flows by ionic transport. Consequently, an increasing concentration of ions results in higher conductivity.

Conductivity is one of the easiest tests for environmental monitoring. Although it doesn't identify the specific ions responsible for conductance, it does quickly determine the total concentration of ions in a sample. This wildcard provides an easy way to meter any conductivity changes using a microcontroller. This makes it very simple to add conductivity sensing to your existing instrumentation.

Here are a few of the kinds of measurements you can perform using the Wildcard:

  • After calibration, you can measure the concentration of unknown samples in an aqueous solution.
  • You can qualitatively compare the difference between the ionic and molecular nature of substance in aqueous solution. This can include differences in strength of weak acids and bases, or the number of ions that an ionic substance dissociates into per formula unit.
  • You can measure changes in conductivity resulting from photosynthesis in aquatic plants, owing to the resulting decrease in bicarbonate-ion concentration from carbon dioxide.
  • You can monitor the rate of reaction in a chemical reaction in which dissolved ions and solution conductivity varies with time due to ionic specie being consumed or produced.
  • You can do a conductivity titration to find when stoichiometric quantities of two substances have been combined.
  • You can determine the rate at which ionic species diffuse through a semipermeable membrane, such as dialysis tubing.
  • You can monitor total dissolved solids in an aquarium containing aquatic plants and animals, as their concentrations change with photosynthesis or respiration.
