Abstract
Automated test equipment is provided that performs quantitive tests and operational checks on respiratory protective devices including self-contained breathing apparatus (SCBA). The testing device is comprised of a bench-top instrument cabinet containing electronic, electro-mechanical, and pneumatic components, a test head with the likeness of human form attached on top of the instrument cabinet, a detachable computer keyboard, and a pneumatic manifold and hose assembly. With the present invention, a layman operator can determine the readiness of the SCBA equipment for service. The present invention can also be used as a diagnostic tool during maintenance procedures.
