Abstract
A gauge measuring percent oxygen by simultaneously measuring oxygen partial pressure and ambient atmospheric pressure with solid state transducers. Two electrical signals obtained from the transducers are combined in a summing amplifier in accord with an empirically determined relation to yield a percent oxygen value which is displayed. The gauge has provisions for using an internal oxygen partial pressure transducer or an external probe connected to the gauge by a cable.
