The MKS Granville Phillips 307 Vacuum Gauge Controller (VGC) measures pressures from 5 x 10^-11 Torr (6.6 x 10^-12 mbar or 6.6 x 10^-10 Pa) to atmosphere, depending on (PCB) printed circuit board optional modules and transducers used. The New 307 (VGC) for sale in its simplest form as pictured runs two ionization gauges (IG) Glass Tubulated or Nude (NOT UHV) one ion gauge at a time, in the range of 2 X 10^-11 Torr. It is a left mount, side by side with power supply for 19 inch rack and comes with AC Power Cord and Power Supply/Control Unit Power Cable. With OPTIONAL Modules the 307 Vacuum Gauge Controller can operate two ion gauges (IG) sequentially, along with two Convectron gauges (CG) or two thermocouple gauges (TC) simultaneously. Pressure readout is via 3 front panel displays, analog output, and available computer interface. The 307 (VGC) is a modular instrument which can be easily customized to fit most user's exact needs.

Infrequently used controls are housed behind a hinged front panel, reducing front panel clutter and allowing the control unit to reside in a half-rack space. The power supply is housed in a separate enclosure and may be rack-mounted alongside the control unit. Reliability is increased by removing power dissipation from the control unit enclosure, which needs no ventilation. Remote mounting of the power supply minimizes heat generated in the user's instrument rack and thus increases reliability of components. This is an MKS Granville Phillips 307 Vacuum Gauge Controller, Cables, sensors/transducers and PCB Module Interface Cards are available but sold separately on this website.
