An electrochemical-sensor system for real-time flow ...

· This resulted in a modification of the fluid-flow conditions for the DEX valve-equipped strip sensors as measured by the electrochemical-sensor system. The presence of DEX valves reduced the flow rate in the pre-valve region of the strip sensor; this then increased in the second part, once the solution was allowed to break through the DEX barrier. The change in the fluid-flow conditions ...

Carbon Monoxide Gas Sensor Principle - Inst Tools

Electrochemical-type gas sensor are amperometric fuel cells with two electrodes. The basic components of two electrode gas sensors are a working (sensing) electrode, a counter electrode, and an ion conductor in between them. When toxic gas such as carbon monoxide (CO) comes in contact with the working electrode, oxidation of CO gas will occur on the working electrode through chemical reaction ...
