Book excerpt: The various designs of mercury barometers and manometers are briefly described, with a more extended discussion of the various design elements which may affect the achievable accuracy.Sources of error in measuring pressures are described in considerable detail, particularly for portable instruments, including sc * ale, temperature, gravity, capillarity, vacuum errors and return gas column.Methods of minimizing those errors and of making the corrections, including extensive tables, are presented.Standard conditions are defined and the pertinent properties of mercury given.The paper contains 65 literature references.(Author).
