With a single gauge tube and controller, the Granville-Phillips 275 Convectron Gauge provides pressure measurement over 6 decades from 1 millitorr to 1000 Torr, or from 1 x 10-3 mbar to 1000 mbar. The gauge tube contains a heat loss sensor which utilizes conduction cooling to sense pressure at lower pressures. At higher pressures, it utilizes convection cooling in which gas molecules are circulated through the gauge tube by gravitational force. Ambient Operating Temperature: 1 millitorr to 1000 Torr, or 1 x 10-3 mbar to 1000 mbar, for N2 using a single gauge tube and controller.
