The present invention relates to a reference electrode of a COD measuring device comprising: an upper tube, where an upper part and a lower part are opened, and an electrode supplementary liquid is filled in an inside; an electrode terminal, which is connected with an upper part of the upper tube; a lower tube, where a ceramic holder is installed in a lower part and an electrode supplementary liquid is filled in an inside, and where a lower part is inserted into a reaction bath, in which a sample is stored, and where an upper part surrounds a lower part of the upper tube, and where an inside surface of an upper part is separated from an outside surface of a lower part of the upper tube at constant intervals; a silicone finishing material for connecting the upper tube and the lower tube by being filled between the outside surface of the lower part of the upper tube and the inside surface of the upper part of the lower tube; a radiator panel, which is installed to surround an outside surface of an upper part of the lower tube, and where a material consists of an aluminum; and a platinum wire, which is installed to cross an inside space of the upper tube and the lower tube. The reference electrode of the COD measuring device is provided to minimize an error of a measured value since heat due to a temperature rise of the electrode supplementary liquid is emitted into an outside effectively. |
