Conductivity Meter Calibration
What does conductivity measure and how is conductivity measured?
Conductivity meters measure the ability of a solution to conduct an electrical current. The ions in a solution allow the solution to be conductive, and the higher the number of ions, the higher the conductivity.
Conductivity is measured by placing 2 electrodes at a fixed distance apart and applying an alternating current to the electrodes and measuring the resistance from the electrons flowing from one electrode to the other.
These results are determined by placing the sensor in an accurate known conductivity solution, at a controlled temperature.
What unit is conductivity measured in?
Conductivity is measured in S/cm (siemens per centimetre)
mS/cm (thousandths of a siemen per centimetre)
µS/cm (millionths of a siemen per centimetre)
