Connector which provide conduits between a sealed environment and an exterior of the environment includes a housing, a plurality of internal conduits extending from a first side of the housing, each adapted to communicate with a respective sampling device situated in the sealed environment, and a single external conduit extending from a second side of the housing opposite the first side and adapted to communicate with a measurement device exterior of the sealed environment. The housing is constructed to enable each internal conduits to alternatingly align with the external conduit such that each sampling device is able to communicate with the measurement device. By providing a connector which is able to provide a flow passage between multiple sampling devices and a single measurement device, at different times, it is not necessary to enter the sealed environment in order to configure a single sampling device in communication with the measurement device.
