Precision Balances (Under Development)
Description
From our Glossary of Terms: PRECISION BALANCE — a scale constructed for a high degree of sensitivity. The term covers a range of instruments: Chemical balance, Analytical balance, Assay balance, Semi-micro, and Ultra-micro balance, in ascending order of sensitivity, from about 1 in 100,000 to 1 in 1,000,000,000 at maximum capacity.
A precision balance is typically in a glass case where the front (and sometimes the back) panels slide up for access to the scale. As the sensitivity increases, it is common to have mechanisms that can add or subtract weight without needing to open the panels.
