Varian Agilent UHV-24 Nude Bayard-Alpert Ionization Gauge, open gauge, Dual Thoria Iridium Filament, 2.75 inch CFF ConFlat Flange, 1×10-3 to 2×10-11 Torr Pressure Range, Maximum Bakeout Temperature: 450 °C

The Varian Agilent UHV-24 Nude Bayard-Alpert Ionization Gauge is a rugged, open gauge with broad-range operating pressure abilities, Thoria-Coated Iridium Filament, 2.75 ConFlat Flange, 1×10-3 to 2×10-11 Torr Pressure Range, Maximum Bakeout Temperature: 450 °C.

The UHV-24 Nude 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 UHV-24p Nude Ionization Gauge 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 filament is field replaceable. Nude gauges are recommended for bakeable, all-metal, ultra-high vacuum systems where maximum exposure to the vacuum gives the highest possible accuracy. The UHV-24 ion gauge is easily interfaced with Varian's XGS-600 gauge controller for integration into a variety of vacuum systems, or for use as a stand-alone pressure measurement tool.
