Product Description


The Smart Q Conductivity Sensor is used to measure the conductivity of a solution.

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.

The Conductivity electrode is manufactured from epoxy and has graphite plate electrodes. This construction offers good durability in field use. It is ideal for measuring salinity and changes in conductivity of a water sample. The sensor cannot identify the specific ions that are present, but can be used to determine the total concentration of ions in a sample.


2-minute - conductivity sensor


Teaching applications:
  • Ionic studies
  • Titrations
  • Polar non polar solutions
Extension and advanced ideas:
  • Diffusion across membranes
  • Diffusion across membranes

  • 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.


  • Use analytical water to maintain and wash electrode
  • Non polar solvents e.g. pentane, hexane will damage the electrode
  • Built -in automatic temperature compensation. Cell constant tolerance: ±20%

    What is the pH of water? (Chemistry (11 -14) eBook)
    In this investigation one simple measurement is used to compare the pH of water samples. Does the pH tell us anything about water quality, safety?

    Sodium hydroxide - acid conductance titration (Chemistry (14-18) eBook)
    An alternative titration method, using conductance to find the isolectric point.

    Sodium hydroxide - acid conductance titration (Chemistry (14-18) eBook)
    Alternativer titration using change in conductance to find the isoelectric point. A drop counter is used for maximum accuracy

    43 Barium hydroxide conductivity titration (Chemistry (14-18) eBook)
    The reaction between barium hydroxide and sulphuric acid produces a precipitate of barium sulphate. the creation of the precipitate alters the conductance of the reaction mixture giving a good alternative titration practical. 

    Conductivity and ion number (Chemistry (14-18) eBook)
    Conductivity in a solution depends upon the presence of ions in the solution.Use conductivity sensor to monitor the rate of change per unit of addition. Relate back to number of ions produced on solvation.
