Description

The Granville-Phillips Model 330 Ionization Gauge Controller is reliable, easy to operate, easy to service and moderately priced. The 330 with switchable, variable emission currents provides the advantage of long filament life, excellent immunity to electrical noise and easily read pressure display.

Bayard-Alpert style gauges have become the standard for accurate measurement of vacuum in mass spectrometers. In some instances, a mass spectrometer may be shipped without a vacuum gauge since it is an optional accessory (such as in the Hewlett Packard 5971 Mass Spectrometer). The mass spec user can easily add the controller at a cost significantly less than purchasing directly from the mass spectrometer manufacturer.

Often the user may want to add additional gauges to better visualize the operation of the mass spectrometer. On magnetic sector instruments or other mass spectrometers where the source and analyzer are differentially pumped, two ion gauge controllers would be advantageous to separately monitor the vacuum in both the source and at the analyzer (multiplier section). This will enable the quick diagnosis of pumping and vacuum problems for optimum instrument performance and maximum electron multiplier life.

An Ion Gauge Controller can easily be added to the Hewlett Packard 5971 mass spec as shown on the right, by inserting the Ion Gauge Adaptor between the NW25 flange on the mass spec and solenoid valve/calibration vial. The Ion Gauge Adaptor contains NW25 flanges on both ends to clamp into the H.P. 5971 as shown, and a 3/4" Cajon 'O' Ring fitting to attach the ion gauge tube. Also included with the Ion Gauge Adaptor is one centering ring, and one clamp. A complete set up for the H.P. 5971 as shown would include one of each of (1) Model 330 Ion Gauge Controller, (2) Ion Gauge Adaptor, (3) G75K Ion Gauge Tube and (4) 330-10' cable.

Additional flanges or ion gauge adaptors are described elsewhere in this catalog, or Scientific Instrument Services can custom machine an adaptor to your requirements. If you have special requirements, please call or write with the specifications you require.
