Description
Granville-Phillips Vacuum Gauge Controller for Versatile, Accurate Pressure Measurement
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.
* VGC340 Only: Purchase cables and tubes separately.

Ion Gauge Tubes, Bayard-Alpert Type Bayard-Alpert Design and Dual Tungsten or Burn-out Resistant Iridium
Agilent/HP MS 5970 MSD® and 599X Series Filament New filaments for your Agilent 5970 MSD.
Convectron Series 275 Vacuum Gauge The Granville Philips Convectron Gauge tube used on the 5971 and 5972 mass spectrometers is available from S.I.S. This is a direct replacement for the HP original and screws into the fitting shown above.
PTFE Ferrules for Ion Gauge Tubes They are available in two compositions, PTFE and Glass filled PTFE.
Agilent (Hewlett Packard) Mass Spec Ion Gauge Tubes Our standard G75K Bayard-Alpert ion gauge tube will fit all models of HP mass specs except the HP5989 MS Engine.
PTFE, Glass Filled PTFE Ferrule for Ion Gauge Tubes These 3/4" PTFE Ferrules are used to install Ion Gauge Tubes.
Santovac 5P Ultra and polyphenyl ether vacuum pump fluid Santovac 5P Ultra has the same properties of Santovac 5 but guarantees minimal amounts of the 3 and 4 ring polyphenyl ethers; less than .02% and .1% respectively and for ultra-clean applications such as
mass spectrometry.
Inland 45 Mechanical Pump Oil Inland 45 is the highest quality rough pump oil you can use for your mass spectrometer.
