The Granville Phillips 330 Ionization Gauge Controller measures pressure from less than 1 x10-10 to 1 x 10-1 torr from a single ionization gauge and displays pressure readout via a front panel display and analog output. The 3 1/2" high modular controller is available as a bench mount or space saving half-rack unit.
This used ionization gauge controller will be fully refurbished and will meet Granville Phillip's performance specifications.
Granville Phillips 316 Convectron Vacuum Gauge Controller allows you to measure pressure at three points in a vacuum system simultaneously. The compact 3 1/2" high half-rack controller replaces up to three singe controllers, saving rack or bench space.
