Analytical Balance

Description:

Christian Becker introduced the Projectomatic precision balance in the early 1950s. The case of this example is aluminum, with glass sides and top, and drawer in the bottom. The beam is aluminum; the knife edges are agate; the pans are stainless steel. One inscription on the handle reads “Christian Becker.” Another reads ”Christian Becker / Clifton, New Jersey / Made in U.S.A. Serial no. A-5853.” According to the firm, the Projectomatic “makes possible automatic weighings from 1/10 mg to 100 mg, the results of which may be read on the magnified image of the scale which is projected onto a conveniently located screen.”
