Arnold Beckman informs J. H. Rushton that the Model G oxygen meter is ready for testing, but the Model F is not. An order has been received from the Linde Company, but not fulfilled, and an experimental instrument was supplied to SAM Laboratories in New York for use in the Manhattan Engineers Project. Beckman notes a series of expenses beyond the contract amount and his personal contribution of over $2000 to the project.

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, and preventing blindness in newborn babies.
