ABSTRACT:
A disk-shaped thin plate or a long-sized thin plate having a roll appearance housed in a casing in which openings for penetration of test substance are formed and on which diffusion-limiting membranes are adhered to cover each openings. Also a driving mechanism for moving the thin plate is provided with the casing. The casing thus houses the thin plate and is provided with the driving mechanism and is positioned in a test apparatus body having a concentration measuring electrode therein. Multiple measurments of concentration of a test substance are carried out by moving the thin plate by the driving mechanism to position the diffusion-limiting membrane having the test solution deposited thereon to the position available to contact with the concentration measuring electrode, while keeping the casing placed in the test apparatus body. As a result, a plurality of measurements of concentration of the test substance is carried out easily.
