Embodiments of the disclosure relate to capillary controlled gas sensors comprising a top cap assembly, wherein the top cap assembly is operable to reduce the effects of condensation and pressure changes on the effectiveness of the gas sensor. The top cap assembly comprises a capillary controlled gas flow path, a bulk flow control assembly, and a raised boss surrounded by a moat.

Gas sensors with structure to resist signal losses due to condensation

A sensor with a sensor housing or body, a plastic molded table positioned in the sensor housing; and a counter electrode carried on a first end of the table.

Support for electrode stack and provision for venting of a gas sensor using an internally mounted table

A method of improving performance of electrochemical gas sensors includes cycling potentials applied to one or more of the electrodes of the respective sensor(s) to improve performance of a different electrode. In a process for treating a reference electrode, potentials can be applied to working and, or counter electrodes so as to modify the environment in the vicinity of the reference electrode. An apparatus can carry out the method automatically.

Apparatus and method of regenerating electrochemical gas sensors

An electrochemical gas sensor is disclosed which comprises a gas sensing electrode and a counter electrode disposed within a housing, the housing having an aperture for gas ingress, the gas sensing electrode and counter electrode being separated by a region containing electrolyte, and means for connecting the gas sensing electrode and the counter electrode to a sensing circuit. An electrolyte-absorbing element is disposed inboard of the aperture, between the housing and the gas sensing electrode, in order to absorb electrolyte passing through the gas sensing electrode whilst maintaining a gas path through the electrolyte-absorbing element.
