Oxygen Analyzer

Usage conditions apply
In the late 1930s, Linus Pauling realized that he could use the fact that oxygen is affected by magnetic fields to measure the oxygen content of a sample of air. After building a few prototypes, Pauling asked Arnold O. Beckman, his colleague in the chemistry department at the California Institute of Technology, to develop a commercial model. Arnold O. Beckman, Inc. was formed in 1942, expressly for this purpose; and Pauling oxygen analyzers were widely used in submarines and aircraft during World War II. The Model D2 was introduced in 1956; and the Model E2 a few years later. The inscription on the front of this example reads “Arnold O. Beckman Inc. / OXYGEN ANALYZER / MODEL E-2.” A tag on the back reads “Ser. No. 16.”
