Overview
Overview
The 370121 Stabil-Ion® Bayard-Alpert Hot Cathode Vacuum Gauge features a 2 x 10-11 - 999 Torr vacuum measurement range and a 2.75 inch CF flange fitting. It is the most accurate Bayard-Alpert style hot-cathode ionization vacuum gauge featuring an all metal gauge tube that eliminates glass breakage, glass decomposition, or helium permeation. The 370 Stabil-Ion® Bayard-Alpert Vacuum Gauge complete electrostatic shield and grounded metal gauge tube housing provide a stable electrical environment and shield against external electrical influences. 370 Stabil-Ion® Bayard-Alpert Vacuum Gauge's precision-wound, stress-relieved grid retains shape even after high temperature degassing and burnout resistant tensioned filaments remain in position over time to enable long-term repeatability.
