Granville Phillips 358 Micro Ion High Vacuum Gauge Controller
These Granville Phillips (Model 358) micro ion high vacuum gauge controllers can be ordered to operate a micro ion and dual convectron gauges simultaneously. Pressure readout is via three front panel displays, analog output, and available computer interface. The micro ion gauge measures high vacuum pressure from 5x10-2 to 10-10 Torr while the convectron sensors are typically used to measure roughing line vacuum pressure from atmosphere to 10-4 Torr.
