Overview
Overview
The 355001-YA Micro-Ion® Bayard-Alpert Hot Cathode Vacuum Gauge features a Yttria-coated Iridium filament for a 5 x 10-10 - 5 x 10-2 Torr vacuum measurement range, and a 3/4 inch tube port. 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.
