Granville-Phillips® 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauges are the smallest Bayard-Alpert style gauges. They are more rugged and wider range than glass gauges. In addition, they generate less heat and provide greater burnout resistance.

The Micro-Ion Gauge is the world’s smallest ionization gauge where pressure measurement is based on the amount of ion current that is generated when energized electrons collide with gas molecules in the gauge. High performance in a small volume is achieved through a number of enhancements including its patented dual ion collector design that optimizes electron motion and ion collection. Dual filaments provide extended lifetime by running both filaments simultaneously at a lower current, and avoid unscheduled downtime by using the second filament as a backup. Ultra-clean construction, including vacuum firing of all components and assembly in a Class 100 cleanroom environment ensures rapid, repeatable response during vacuum chamber pumpdown.
The Series 358 Micro-Ion® Controller is designed specifically to obtain the highest performance from the Micro-Ion® Gauge. It is capable of measuring from a lower limit in the 10-10 Torr range (10-10 mbar, 10-8 Pa) to 5x10-2 Torr (7x10-2 mbar, 7 Pa). Pressure measurements can be extended to atmosphere with the Dual Convectron® Gauge Option.
