Many factors affect the measurement of pressure in the ultra-high vacuum regime. The operating theory of the various hot filament and cold-cathode gauges will be briefly reviewed, followed by a more in-depth discussion about the factors that affect the different gauges. Operational behavior and stability of both hot filament gauges, such as the Bayard-Alpert, Modulated BA and Extractor gauges, and cold-cathode gauges, particularly the inverted magnetron gauge, will be addressed.
