ABSTRACT:
An electrochemical gas sensor having a flexible membrane mounted at the sensing end of a housing, to dissipate increased electrolyte pressure, a small sensing electrode cooperating with a relatively thick porous sheet of polytetrafluoroethylene (PTFE) supported by the flexible membrane, and the housing also containing an electrolyte and a counter electrode, with suitable circuitry connected to the electrodes for quantifying the current generated by the sensor.
