The present invention relates to an apparatus for measuring conductivity with four electrodes which includes a container for providing a space for containing electrolyte thereinto and providing a space in which a portion of electrodes is accommodated; the electrolyte contained in the container to measure conductivity thereof; four electrodes spaced apart from each other in such a manner as to be partially submerged into the electrolyte to measure the conductivity of the electrolyte; and an insulation packing unit adapted to piercedly insert the four electrodes thereinto in such a manner as to allow the four electrodes to be insulated from each other and to seal the top of the container, wherein the four electrodes partially protrude from the top of the insulation packing unit. According to the present invention, the conductivity of the electrolyte can be measured without any limitation on temperature and pressure, and since it is measured in the sealed state, the temperature of the electrolyte is uniformly distributed. Further, the conductivity can be measured through the change of the temperature of the electrolyte in the state where the introduction of impurities is suppressed, the change in quality of the electrolyte can be prevented, the preservation period of the electrolyte can be extended, the variation of the electrolyte contained in the container can be observed, and since the container in which the electrolyte is contained is sealed in the state where the four electrodes are fixedly insulated from each other, the leakage of the electrolyte can be suppressed to safely measure the conductivity of the electrolyte. |
