Abstract

A sensor includes a sheath (26) that is elongated along a longitudinal axis (34); a spacer (30) positioned within the sheath and defining first and second channels (31-33) having lengths that extend along the longitudinal axis; a first elongated member (21) positioned within the first channel (31); and a second elongated member (22) positioned within the second channel (32). The first elongated member (21) includes an active surface (21a) forming a working electrode and the second elongated member (22) including an active surface (22a) defining a counter electrode.
