Conductivity sensor

The Conductivity sensor ML57m measures conductivity of a solution in the range between 0 to 20,000 µS/cm. The Conductivity sensor consists of a conductivity electrode and an amplifier. The Conductivity electrode is a simple ABS-bodied 2-cell graphite type.

Conductivity is one of the easiest environmental tests for aquatic samples. Even though it does not indicate specific ions that are present, it does quickly determine the total concentration of ions in a sample. It can be used to perform a wide variety of experiments to determine the changes in or levels of total dissolved ions or salinity:
• Confirmation of the direct relation between conductivity and ion concentration in aqueous solutions. Concentration of unknown samples can be determined.
• Measurement of changes in conductivity resulting from photosynthesis in aquatic plants, with the resulting decrease in bicarbonate-ion concentration from the carbon dioxide consumption.
• Monitoring the rate of reaction in a chemical reaction in which dissolved ions and solution conductivity vary with time, due to ionic species being consumed or produced.
• Performing a conductivity titration to determine when stoichiometric quantities of two substances have been combined.
• Finding the rate at which ionic species diffuse through a membrane such as dialysis tubing.
• Monitoring changes in conductivity or total dissolved solids in an aquarium containing aquatic plants and animals. These changes could be due to photosynthesis or respiration.

The Conductivity sensor ML57m is a digital sensor (on-sensor digital conversion), which gives calibrated values of the measured quantity. This sensor can only be connected to the CMA MoLab interface and not to other CMA interfaces such as VinciLab, CoachLab II+ or EuroLab.

Technical specifications of the sensor are described in its User's guide.
