<p>A partially disposable, partially reusable polarographic sensor includes a fixed membrane (108) and gel electrolyte (109) in the disposable portion, and includes all electri- cal/metalic parts in the reusable portion (106). The disposable portion comprises a housing (101) having a flow chamber (104) for fluids to be monitored, adjacent to which is the membrane (108). Behind the membrane (108) is the gel electrolyte (109), and a screw structure (111, 112) for engaging the reusable part (106). In turn, the reusable part (106) employs a matable screw portion (112), and a fixed, coaxial anode-cathode assembly, which when mounted to the disposable portion, engages the membrane (108).</p> |
