They can be improved fitted to applications where by a superior standard of precision is essential but not to your extent of ultra-precise measurements.
This type of balance makes use of a beam with two knife edges, a person supporting the weighing pan and the opposite acting for a pivot. The unequal arm design permits precise measurements by compensating for the load of the thing remaining weighed.
Stage indicator: It can help to check In case the balance is leveled properly. It makes certain that the balance is over a stable and perhaps surface area for correct weighing.
