MBA-200T Ionization Gauge, Dual Tungsten Filaments (NW40 KF)


Product Description

The MBA-100 is a compact, all-metal high-vacuum gauge for use where measurement precision and repeatability are equally important, for example laboratory vacuum systems, mass spectrometers, electron microscopes and scientific instruments. A heated filament provides a constant source of electrons for gas ionization, creating superior accuracy and stability, and a wide measurement range from 1 x 10-2 to 1 x 10-9 Torr. Agilent’s unique etched-grid technology provides excellent gauge-to-gauge repeatability, and the small internal surface yields minimal outgassing to ensure accuracy and to protect your experimental process. The MBA-100 is small and rugged to permit easy installation in a closely packed system. The locking electrical connector ensures safe, positive contact, while the plastic housing protects people and nearby equipment from heat. A metal housing provides excellent shielding from electromagnetic interference (EMI) for superior gauge stability. The thoriacoated iridium filament resists burn out, even in the event of an accidental exposure to air. A dual filament model is available for the most critical applications; the spare filament will permit continued pressure measurement until the next scheduled maintenance period. The MBA-100 is easily interfaced with Agilent’s XGS-600 controller for use as a stand-alone pressure measurement tool, or for integration into an experimental or process system. The MBA-200 has two filaments, either thoria-coated iridium or tungsten, for maximum reliability.
