3.7 Accessory Flow-Through Adapter
A flow-through adaptor is available for the Series 335 Oxygen Ana-
lyzer for those applications that require piped-in gases. The adaptor consists
of a sealed chamber where the instrument’s probe is inserted, with two
radially-oriented hose connectors to which supply and vent lines for the
calibration gas are connected. The design provides gas flow over the sens-
ing surface of the cell without contamination by the surrounding monitored
atmosphere.
