ABSTRACT:
A molded one-piece housing for use in fabricating conductivity cells. An electrically nonconducting housing includes an internal partition which divides the interior of the housing into a first region for receiving a test liquid and a second region for receiving a plurality of electrical conductors. Openings through the partition provide passages through which measuring electrodes may project into the first region to establish cell constants of the desired magnitude. These openings are so shaped that they establish a liquid-tight seal between the housing and the electrodes during insertion. By means of this seal the electrodes are held firmly in place during the assembly of the cell. This seal also permits a potting compound to be introduced into the second region without leaking onto and thereby affecting the electrical characteristics of the electrodes.
