The Granville-Phillips® 307 Bayard-Alpert Vacuum Gauge Controller measures pressure, and utilizes pressure-related outputs to control a variety of vacuum system functions and processes. To fit a wide range of applications, the 307 Bayard-Alpert Vacuum Gauge Controller is available in a variety of configurations and prices. In its simplest form the 307 Bayard-Alpert Vacuum Gauge Controller runs a single ionization vacuum gauge in the range from 1 x 10^-10 to 1 x 10^-1 Torr.

• Operates MKS Granville-Phillips® 274 Bayard-Alpert Ionization Vacuum Gauges
• Sequential operation of a second ionization gauge
• Up to six process control set points are available
• Increased reliability due to conservative design and cooler operating temperature
• Electric shock danger significantly reduced by using only low voltage circuits
