Conductivity Pack   Home / SmartQ Sensors  

The Conductivity pack is both the Conductivity adapter (3135) and the Conductivity electrode (3136).

This sensor can be set to any of four ranges enabling accurate measurements from very low ionic sources such as deionised or distilled water to very highly conductive solutions including sea water.

  • Titrations of strong versus weak acids
  • Electrolytes and Non-electrolytes
  • Finding the equivalence point
  • Difference between ionic and molecular compounds
  • Diffusion of ions through a membrane

  • Environmental testing for salinity, total dissolved solids or general conductivity in water samples

The electrode incorporates an in-built temperature sensor that is used to compensate for changes in the conductivity of solutions with temperature.

The electrode should be kept clean and free of deposits and should therefore be washed between samples, and after use to prevent build up on the graphite plates.
