PURPOSE:To continuously measure the concn. of oxygen in a small amount of a liquid specimen with high accuracy, by providing a magnetic stirrer rotated by a magnetic field rotary means and a constant temp. heating means to the electrode unit constituting the bottom surface of a container. CONSTITUTION:The magnetic rotary device 24 provided to the underside of the electrode unit 22 fixed to the lower part of a glass container 27 is constituted so that the magnetic stirrer 30 in the container 27 is rotated by the rotary magnet 25 rotating by the motor 26 in said rotary device 26. Since a housing supporting a measuring electrode for measuring the concn. of oxygen and a reference electrode is heated to predetermined temp. and a protruded part 1a is provided to a container support 1, the reaction solution 110 stirred by the stirrer 30 in the container 27 is efficiently held to predetermined temp. By the apparatus thus simplified and miniaturized, the concn. of oxygen can be continuously measured with high accuracy. |
