<P>PROBLEM TO BE SOLVED: To make an electrolytic current stably measurable according to a polarograph system or a galvanic cell system even in an environment where a high pressure sample liquid flow of a water main or the like is present. <P>SOLUTION: The electrolytic current measuring instrument is equipped with a substrate 1 which is inserted in a sample liquid, the detection pole 2 provided to the substrate 1 and the impeller 5 present under the substrate 1 and having a rotary shaft 5a almost parallel to the insertion direction of the substrate 1. The electrolytic current measuring instrument is characterised in that the impeller 5 is constituted so as to form the centrifugal flow F2 of the sample liquid, which goes in a radial direction from the rotary shaft 5a, between the impeller 5 and the substrate 1 by its rotation, and the detection pole 2 is arranged so as to come into contact with the centrifugal flow F2. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
