IR Filament Glass Ion Gauge Tube, Bayard-Alpert Style, 1 inch Port, Vacuum Pressure Gauge These iridium glass ion gauge tubes have a 1 inch OD vacuum connection port and an operating range from 1x10-3 to 2x10-10 Torr. These ion gauge tubes are compatible with most modern hot cathode ion gauge tubes. They have a sensitivity of 10 Torr-1 and standard operating voltages (collector 0 VDC, Grid +180 VDC, filament -30 VDC with 5 VAC). The thoria coated iridium (IR) filament configuration can be used in any clean application, but is particularly practical in potentially oxygen rich environments. All IR filaments have a thoria coating, which increases electron emission to approximately the same level as tungsten filaments. Iridium filaments, however, can be strongly degraded by metallic or organic contaminants, resulting in poor accuracy (filaments are easily poisoned by oil back-streaming from diffusion or mechanical vacuum pumps). Thoria coated IR is very resistant to oxidation, and can even tolerate brief exposure to atmosphere during operation and will not damage or shorten the filament life. Iridium ion gauge tubes can typically be identified by the single white hair-pin shaped filaments and have four external leads at the plug end. Our replacement ion gauge tubes work with most hot cathode ion gauge controllers made by Granville Phillips, MKS Instruments, Perkin Elmer, Varian, & Veeco. Typically Works With: Granville Phillips Models 260, 270, 280, 303, 306, 307 330, 340 ,350, and others.
