370 Stabil-Ion® Hot-cathode Ionization Vacuum Gauges
Overview
Granville-Phillips® 370 Stabil-Ion® Bayard-Alpert Vacuum Gauges are the most accurate Bayard-Alpert style hot-cathode ionization vacuum pressure gauges featuring an all metal gauge tube that eliminates glass breakage, glass decomposition, or helium permeation. A complete electrostatic shield and grounded metal gauge tube housing provide a stable electrical environment and shield against external electrical influences.
- Ionization gauge for accurate vacuum measurement from the 10-11 Torr range
- Convectron Gauge option extends pressure measurement to atmosphere
- Stabil-Ion Gauge has memory module with calibration data
- Ultra-clean gauge construction allows rapid response during pumpdown
- Dual filaments increase equipment uptime
