Abstract

Dr. Erhard Mettler Switzerland was the first to apply the idea of having a balance with one pan and a beam with a constant load in 1945. The load on the beam is kept the same irrespective of the mass of the object weighed on it. It was a damped balance giving a constant indication in a short period. Because of the ease in getting mass of a body without much calculation, this type of balance became very popular in mid-fifties of twentieth century.
