Eliminates capillary depression error. Easily cleaned. Accuracy plus or minus 3%. A tilting gauge which maintains a constant overflow head of mercury and maintains capillary depression of the meniscus. Readings don't bounce. Removable and interchangeable measuring tube permits accurate…

Double tube vacuum manifold with #15 o-ring joints at both ends. Available in either a 3 or 4 port configuration with 4mm bore glass double oblique stopcocks. The ports can be ordered in 14/20, 24/40 standard taper or #15 o-ring joints. The distance between ports is 210MM which allows for use of…

Accurate to within plus or minus 3%. The McLeod gauge is the most convenient and economical instrument for measuring low pressures from 1 micron up. The ACE McLeod gauge is offered in four ranges, so that it is possible to accurately measure any pressures between 1 micron and the highest reading on…

A tilting gauge with a constant zero overflow which eliminates the capillary-depression error from an expanding meniscus. Once the zero line of the scale is aligned with the tip of the closed capillary, it is only necessary to bring the gauge to an upright position and read the scale behind the…

A simple form of vacuum gauge, not mounted, but supplied with graduated scale. Mercury NOT supplied.
