Abstract
An electrical conductivity meter comprises a measurement tube formed of an electrical insulation material and through which a fluid of a measurement target flows, a first electrode formed on an outer peripheral surface of the measurement tube, a second electrode connected to a common potential and in contact with the fluid, a resistor in which one end is connected to the first electrode, a voltage detecting portion that detects voltages of a signal generated in the first electrode due to an input of an AC signal to the other end of the resistor, and an electrical conductivity calculating portion that calculates an electrical conductivity of the fluid based on an amplitude of the voltages detected by the voltage detection circuit.
