Bayard-alpert gauge
WebGranville-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. WebETI BAYARD ALPERT GAUGE MANUAL REV - Page 6 of 11 4.0 TECHNICAL INFORMATION 4.1 PRESSURE INDICATION Ionization gauge controllers actually measure the positive ion current in amperes from the gauge tube but the readout is in pressure units. Even more specifically, these pressure units are direct reading only for the gas
