49,289, ABSTRACT OF THE DISCLOSURE, A conductivity cell wherein thin film or foil electrodes are supported in a case or holder and are separated by an electrically insulative spacer member. A small portion of each electrode together with an exposed surface of the spacer member forms a channel in which thin films of an electrolyte may be deposited from a measured environment and with the electrodes being connected to a conductivity circuit the conductance of the thin film may be measured. If the electrolyte and its concentration are known, the film thickness and deposition rate in the channel may be obtained.
