A New Micro-Balance and Its Use (Classic Reprint)

Hans Pettersson

Excerpt from A New Micro-Balance and Its Use Most weighing balances can be classed either as elastic balances or as lever balances. On instruments of the first type the load is suspended from an elastic structure of some kind, generally a spring coil, which becomes deformed until the elastic forces caused by the deformation counteract the downward pull of the load. The vertical displacement of the latter is read on a scale, and the instrument is standardized by producing different scale-deflections with a set of weights.
