It is the regular No. 1105 Becker Balance equipped with chain, and gives direct 

 rapid reading without rider or small weights. 



Polished mahogany case, front sliding frame, counterpoised. Mounted on black 

 plate glass. 



After all the necessary large weights up to 50 milligrams are placed on the pan, 

 the weighing from 50 milligrams to 1/10 of a milligram can be concluded without 

 opening the balance or using the arrest, eliminating the necessity of reading and re- 

 placing all small weights or the handling of a rider with a consequent enormous saving 

 of time. 



One end of the weighing chain is hung from an arm of the scale beam, and the 

 other end from a slide-block which is moved up and down on a vertical graduated 

 scale. As this block is raised, more of the weight of the chain is taken from the 

 beam and hangs from the slide-block which forms a stationary support for holding 

 the inactive part of the chain. As the slide is lowered a greater proportion of the 

 weight of the chain is transferred to the beam. 



Price $175.00 



NOTE: We have produced specially designed sets of weights for the Chainomatic 

 Balances. For full details, see page 32.
