Total and Partial Pressure Measurement in Vacuum Systems

The book "Total and Partial Pressure Measurement in Vacuum Systems" offers a comprehensive analysis of the theory and practical aspects of pressure measuring devices used in vacuum systems. It is aimed at professionals in research and industry who require a deep understanding of the operation and requirements of modern vacuum technology. The author, John Henry Leck, discusses various types of pressure measuring devices, particularly mechanical types that are considered absolute measuring instruments. These devices measure pressure directly by the force on a column of liquid or a solid surface. The book also addresses the latest developments in viscosity and molecular damping technology, which can also be regarded as absolute measuring instruments. Additionally, it discusses indirect measurement methods and their necessity for calibration against absolute standards. The detailed examination of the McLeod gauge, regarded as the most sensitive absolute measuring instrument, emphasizes the significance of this work as a reference standard in vacuum technology.
