PURPOSE: An apparatus for measuring a characteristic value of a permanent magnet is provided to improve the reliability by measuring characteristic values of samples within a chamber and comparing the characteristic values to each other. CONSTITUTION: A chamber(110) includes a temperature sensor, a humidity sensor, a heater, and a humidity controller. A plurality of rotary tables(120) are installed in the inside of the chamber. A plurality of through-holes are arranged on the rotary tables. A rotary shaft is formed at a center of the rotary table. An index driver is used for rotating the rotary shaft as much as an angle between the through-holes. A plurality of transferring jigs(150) are installed at lower parts of the rotary tables. A jig transfer unit transfers the transferring jig. A detector(140) is installed at an upper part of the rotary table in order to measure a characteristic value of a permanent magnet. A controller is used for controlling operations of the index driver, the jig transferring unit, the heater, and the humidity controller.
