Installation, Operation & Maintenance Manual
OXYvisor Optical Oxygen Analyzer
Barben Oxygen Sensors (BOS), are sold separately or as parts of an integrated (SCP) package with the
OXYvisor. The sensors consist of a ber optic cable with SMA termination at one end, for connection to the
OXYvisor, and the other end, integrated with a oxygen sensing luminophore to be placed into the process or
sample stream. There are three oxygen sensors, each with unique measurement ranges that can be used with
the OXYvisor; BOS1, BOS2 and BOS3. Their selection and pairing with the OXYvisor will dene the range,
accuracy, and repeatability of the OXYvisor. For additional information on BOS sensors please refer to the
BOS sensor product data sheet.
