This aerial photograph of Beckman's Fullerton plant includes an inscription sketching the company history and facility's use.

The console incorporates Honeywell and Beckman instruments, including an infrared analyzer, automatic stream selector, and gas chromatograph. It may have been fabricated for Advanced Technology Operations contracts with…

This instrument was designed to analyze the atmospheric composition within a spacecraft's cabin during the Apollo missions.

The August 1 date of manufacture on the carbon dioxide sensor preamplifier places this photograph in the latter half of 1962. This instrument was designed for use during NASA's Mercury manned spaceflight 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,…

Beckman’s measurement of carbon dioxide was spurred by many applications. It was in part an outgrowth of World War II era work (such as that which produced Pauling’s oxygen meter) and post-war developments (including…
