The theory of the Absolute Manometer of Knudsen has been developed rigorously according to the revised theory of thermal transpiration which has been established by WU recently. The present theory has been compared with Knudsen's and von Smoluchowski's theories for certain boundary conditions. This paper presents a generalized theory of the Absolute Manometer for any temperature ratios and arbitrary accomodation coefficients on the boundaries.
