電率測定回路。In a rectangular wave electrolyte conductivity measurement circuit, sample hold cuts the waveform rounding of the rising and falling parts of the square wave and holds the wave height value at which the waveform rounding has disappeared after the rising and falling have been completed. A sample-and-hold timing generation circuit is provided in front of the output rectifier circuit, and controls the systematic operation of the sample-and-hold circuit in synchronization with the rectangular wave by a signal from the rectangular wave generation circuit that generates the rectangular wave. A conductivity measurement circuit consisting of a circuit.
