Abstract

A gas sensor comprising a housing and arranged such that a gas flow resistant member engages the housing and is sealably positioned to restrict the flow of gas into the opening leading to the cavity. Where the sensor is installed into a cell holder of the gas analyzer, the cell holder may include a gas flow resistant member opener to open the gas resistant member after being contained therein. In this way, the amount of gas to which the sensor is exposed during the transition period is substantially reduced. Accordingly, the amount of gas that diffuses into the electrolyte solution that would, otherwise, adversely affect the accurate and precise measurement of low concentrations of gas at the early stages of operation, is greatly diminished. As a result, the recovery time required for the excess gas to diffuse from the electrolyte is substantially reduced.
