Abstract: Disclosed is a device for quantitatively analyzing material of a living creature. The device includes an analyzing unit using photometric method, and an analyzing unit using electrochemical method. The device has a socket for mounting a photometric test strip and a socket for mounting an electrochemical test strip, separately or in a body. Also, the test strip may have a recognition electrode formed on a specific position of the test strip. The position of the recognition electrode is determined by analyzing method and target material. When used together with a test strip having the recognition electrode, the device has a terminal for identifying the position of the recognition electrode.
