Abstract
A mask and regulator for a self-contained breathing apparatus (SCBA) having a lens and a nozzle, the regulator being adapted for connection to the nozzle. A bifurcated display is mounted on the regulator for displaying amounts of pressure through a port communicating with the lens on either side of the nozzle. A high pressure connection to the source of breathing gas is connected to a transducer assembly for indicating the pressure to the bifurcated display on the regulator on either side. The display provides pressure values through the exterior of the lens in a bifurcated manner analogous to an arcuate gauge display.
