Electricity conductivity measurement equipment for four terminal resistance measurement method

Electricity conductivity measurement equipment using a four-terminal resistance measurement method is provided to improve the measurement accuracy and to use in the reproducibility evaluation of the measurement readily. Electricity conductivity measurement equipment using a four-terminal resistance measurement method includes a specimen supporting board, a specimen fixing board moving lever(31), and a supply electrode. The specimen supporting board is installed on a supporting board(10). A specimen is placed on the specimen supporting board. The specimen fixing board is installed on a center of the supporting board. A supply electrode part(40) is formed with metal which is contacted to both side of the specimen and applies current, and is moved to left-right directions. A measurement electrode transferring part(20) is coupled to a fixing column to move up and down, A measurement electrode transferring part moving lever(21) moves the measurement electrode transferring part up and down. A measurement electrode(50) is installed under the measurement electrode transferring part and is moved to left-right directions, and measures voltage in the both end of the specimen by a metal material of the lower end. A measurement electrode moving lever(51) moves the measurement electrode in right and left directions.
