MKS Granville Phillips Iridium Filament Glass Ion Gauge Tube, Bayard-Alpert Style, 3/4 inch Pyrex inlet Port, Vacuum Pressure Gauge. MKS Granville Phillips Part Number: 274002 These MKS Granville Phillips 274 Iridium glass ion gauge tubes have a 3/4 inch OD vacuum connection Pyrex Glass 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 MKS Granville Phillips 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 be typically identified by the single white "hair-pin" shaped filaments and have four external leads at the plug end.

MKS Granville Phillips Part Number: 274053 The MKS Graville Phillips 274 Nude Bayard-Alpert Ionization Gauge is a rugged, open gauge with broad-range operating pressure abilities, Thoria-Coated Iridium Filament, KF40 NW40, 1×10-3 to 2×10-11 Torr Pressure Range, Maximum Bakeout Temperature: 450 °C.The Granville Phillips 274 Ionization Gauge, with an x-ray limit of 2x10-11 Torr, provides reliable pressure measurement from 1 mTorr down to 2x10-10 Torr, with reduced performance at pressures lower than 2x10-10 Torr. The Granville Phillips 274 utilizes an extremely thin collector which lowers its x-ray limit to 5x10-12 Torr. As a result, it can measure pressure from 1m Torr down to 5x10-11Torr, with reduced performance at pressures lower than 5x10-11 Torr. Properly mounted nude gauges, where the grid structure protrudes into the vacuum chamber, offer the lowest error in terms of the local vacuum pressure being the same as the chamber pressure. The Granville Phillips gauge is easily interfaced with the Varian’s Agilent XGS-600 gauge controller for integration into a variety of vacuum systems, or for use as a stand-alone pressure measurement tool.
