Granville Phillips Vacuum Gauge Controller

Granville-Phillips Vacuum Gauge Controller for Versatile, Accurate Pressure Measurement

Vacuum gauge controller

  • Uses one Bayard-Alpert Ion Gauge tube and two Convectron Gauge Tubes
  • Resistance Heating Degas
  • Convenient Bench Top Design
  • Three Independent Digital LED Readouts

Granville-Phillips 340 Vacuum Gauge Controller (VGC) measures pressure from less than 1 x 10-9 Torr to atmosphere, utilizing an ionization gauge and two Convectron gauges. Pressure from each gauge is indicated independently on three front panel digital displays and by rear panel analog outputs. Resistance heating degas of the ionization gauge is standard.

Infrequently used controls are housed behind a hinged front panel to reduce front panel clutter. The 3 1/2 in. high controller is available as a compact 8 in. wide bench mount unit.

Excellent efficiency of the integral power supply and low internal power consumption allows the 340 to run cool without requiring ventilation openings in its aluminum enclosure. This helps avoid failures that can be induced by heat or foreign materials.
