Abstract
An electrical conductivity detector is provided with a waveform output unit for supplying an AC signal to a measurement target and a controller for controlling the waveform output unit. The controller executes processing for multiplying the detected wave obtained when the AC signal passes through the measurement target by a reference wave. The controller causes the waveform output unit to generate a waveform with a dummy peak superimposed on an input wave and executes processing for detecting a phase difference. The controller causes the waveform output unit to generate a waveform with no dummy peak superimposed on the input wave and executes processing for correcting the phase difference with respect to the reference wave to calculate the electrical conductivity based on a result of the multiplication processing.
