It is unclear how this model of oxygen analyzer relates to the instrument invented by Linus Pauling (and produced by Beckman) during World War II.

Pictured in this image: a Beckman RAC (Respiratory Analysis Cart); Oxygen Monitor; OMII Oxygen Analyzer; LB-2 Medical Gas Analyzer; RR-2 Respiratory Recorder; and several models of LB-2 Medical Gas Analyzers that each…

Electroencephalographs are used to monitor and record electrical activity of the brain.

Developed from a Linus Pauling design during WWII, the technology behind Beckman Instruments’ oxygen analyzers ended up doing such diverse jobs as monitoring astronauts’ respiration, maintaining packaged food safety,…

Spirometers determine lung capacity and health by measuring how quickly and how much air is inhaled and then exhaled.

This image shows the graphical print-out of the instrument's readings. A respiratory recorder records both oxygen and carbon dioxide levels during respiration.

Spirometers determine lung capacity and health by measuring how quickly respiration happens and how much air is both inhaled and exhaled.
