Special Features:

6 digit counter; pressure reading 0.0-32.0 in hg, 0.0-16.0 psi, 0.0-1100.0 mb; 20 calibration points in 5.0 percent pressure increments; 20 calibration points in altitude

Properties:

An item designed to simulate ascent and descent in a pneumatic system, and to indicate the equivalent altitude at which the baroswitch contacts operate. It also tests elements of open-on-ascent and close-on-descent baroswitch assemblies (either remote or nonremote setting), portions of wiring within the assemblies and pressure checks the complete barometric system of a rocket, guided missile, or the like.
