ABSTRACT:
A partially disposable, partially reusable polarographic sensor includes a fixed membrane and gel electrolyte in the disposable portion, and includes all electrical/metallic parts in the reusable portion. The disposable portion comprises a housing having a flow chamber for fluids to be monitored, adjacent to which is the membrane. Behind the membrane is the gel electrolyte, and a screw structure for engaging the reusable part. In turn, the reusable part employs a matable screw portion, and a fixed, coaxial anode-cathode assembly, which when mounted to the disposable portion, engages the membrane.
