Abstract
An improved contacting-type conductivity measurement system and method are provided. A first conductivity measurement is obtained by driving a contacting-type conductivity sensor with an excitation voltage at a first frequency, a second conductivity is obtained by driving the contacting-type conductivity sensor with the excitation voltage at a second frequency. The first and second conductivity measurements are used to provide a more accurate conductivity output.
