1″ Pyrex, Twin Tungsten Filaments, Brooks Style
Our Bayard Alpert, G100PTA ionization gauge is a 1" glass tubulation, twin tungsten filament gauge. The twin tungsten filaments operate at a very high temperature and are relatively insensitive to contamination found in implanter or sputtering systems. The tungsten filaments are, however, susceptible to failure by oxidation due to poor vacuum or sudden pressurization. Our gauges are most accurate continuous indicators for pressures below 1 x 10-3 Torr. See our Ion Gauge Operating Details and Ion Gauge Cross Reference Guide.
