Abstract

Certain chemical and physical investigations such as the
mechanical analysis of soils by centrifugation require that the
speed of rotation of the centrifuge be precisely determined. For
a cost of approximately $40.00, when used with instrumentation
normally available in research laboratories, the system outlined
provides a vivid, unambiguous indication of the speed of rotation,
the accuracy of which is limited only by the frequency
standard used.
