Abstract
An electrochemical sensing cell includes a planar sensing electrode clamped between a manifold cap and a cover for a container housing the counterelectrode and electrolyte. In the manifold cap, the gas being analyzed flows through a shallow recess into contact with one side of the sensing electrode. The cover includes an opening across which is supported a porous disc saturated with electrolyte. When the cap is secured to the cover, the disc presses against the other side of the sensing electrode to ensure good electrolyte contact therewith. A vent hole in the cover also permits replenishing of the electrolyte without major disassembly of the cell.
