Wide Range Precise Conductivity Measurement without Cell Replacement
Original language description
This paper a little contributes into precise electrolytic conductivity measurements with planar sensors. The novel measuring method was suggested for measurement with IDEs thick-film electrodes. Correction characteristics in wide range of a specific conductivity were determined from a interface impedance characterisation of the thick-film IDEs. The cell constant strongly depends on frequency and conductivity of solutions. A local minimum of the imaginary part of the interface impedance is used for correections to get linear responses. In this minimum a ridge frequency and a cell constant were determined for each measured conductivity. An iteration mode of measurements was suggested to measure exactly in the ridge frequency of the measured conductivityto rich high accurate response. A implementation of the method as microcontroller application can used to built-up microsystem for precise conductivity measurements in concentration range from 10-6 to 1 M without the cell replacement.
