The MINOS oxygen and carbon dioxide monitors were first developed in 1968 and monitored atmospheric conditions in diving habitats, vehicles, and pressure chambers.
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.
This image shows the graphical print-out of the instrument's readings. A respiratory recorder records both oxygen and carbon dioxide levels during respiration.
