3.10 Accessory Flow-Through Adapter
A flow-through adapter is available for the Series 3350
Oxygen Analyzer for those applications that require piped-in gases. The
adapter 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. Refer to Fig 3-7 . The
design provides gas flow over the sensing surface of the cell without
contamination by surrounding monitored atmosphere.
NOTE: If the sensor probe is installed without a constant flow
of gas, it will interfere with the sensor readings and will cause drift
and inaccurate readings.
