BDS-3000 Teledyne

BDS Series of PPB Trace Oxygen Analyzers

In response to the increased importance of accurately and reliably detecting trace ppb levels of oxygen, Teledyne designed a new, high sensitivity Bi-potentiostat Driven Sensor (BDS).

The replenishable BDS is a culmination of an extensive R&D effort in conjunction with several beta tests conducted with key Teledyne users in the semiconductor industry. The BDS achieves greater sensitivity (LDL of 250 ppt), faster response / recovery, and ease-of-use over any previous wet-cell oxygen sensor offering from Teledyne.

    • Teledyne can provide the BDS-3000 in a single 19″ rack mount design or mount two BDS-3000s side-by-side in a single 19″ rack panel, space-saving configuration.


  • The BDS-306 was designed to allow current Model 306WAM / Model 366 Open Cathode PPB / PPM Analyzer users to conveniently replace their existing units with a higher sensitivity drop-in replacement.

BDS Sensor

The BDS design is superior to existing wet-cell oxygen sensors as the bi-potentiostat clearly controls the electrode potential much more precisely than conventional means. This enhanced design also provides the user with a sensor that is faster to respond to oxygen concentration changes and one that is unaffected if left exposed to zero gas for extended periods of time (i.e. no “sleep effects”).

The BDS sensor has a two-year warranty with an expected life of three to five years when used properly. There are no pro-rated warranty issues to be concerned with and the sensor replacement cost, when and if it must occur, is a fraction of other ppb wet cell sensing technologies currently available on the market.
