ANALYTICAL BALANCES
* fast-reading * easy-operating drugged construction ^dependable performance Gram-atic is the family name for 3 analytical balances—macro, semi-micro a n d micro. T h e y are the original one-pan, airdamped, direct-reading balances with 2 (instead of 3 ) knife edges. Mechanically removed weights keep the beam under a constant load, hence eliminate deflection errors a n d assure constant sensitivity over the entire weighing range. When introduced, they were called "the first major improvement in balance design i n more than a century/* T h e combination of automatic weight removal a n d airdamping makes the Gram-atic Balances the speediest available today. Weighings take one-fourth the time of other balances (one-tenth in the case of micro weighings). Most important—the constant-load, constant-sensitivity feature makes the Gram-atic balances accurate!
