Abstract
THE spoon gauge is probably the most satisfactory and easily constructed instrument available for the accurate measurement of pressure differences when the use of a manometric liquid is not permissible. Its sensitivity, however, is limited to a pointer movement of about one millimetre for each millimetre of mercury pressure, or perhaps a little more with very fragile gauges. We describe below an effective design which shifts the sensitivity several decimal places into the high vacuum range.
