Abstract
An electrochemical sensor is provided that includes a housing having an outer wall, a plurality of longitudinal walls disposed within the outer wall, and a reference chamber housing a reference electrode. The longitudinal walls define a plurality of longitudinal chambers. Ionic communication between the target fluid and the reference electrode passes sequentially through each of longitudinal chambers from a first longitudinal chamber to the reference chamber. In this manner, the sensor provides generally a long, tortuous flow path, or salt bridge, between the target fluid and the reference electrode, resulting in a high resistance factor for the sensor.
