ABSTRACT:
A testing device generally includes a housing having an inner cavity and at least first and second housing passageways extending from an environment outside the housing to the inner cavity. The testing device further includes a gas sensor contained within the inner cavity of the housing, the gas sensor having a measurement chamber and at least first and second sensor passageways. The first and second sensor passageways are fluidly connected with the first and second housing passageways in a hermetically sealed manner to prevent the passage of fluids from the inner cavity of the housing to the measurement chamber of the gas sensor.
