precision scales
Exact mass measurers
Precision scales are measuring instruments designed for accurate weight determination, typically sensitive to fractions of a gram.
Laboratory and scientific work requires precision scales; so do jewelers weighing gemstones and pharmacists measuring compounds.
The term emphasizes exactness over the rougher measurements of ordinary kitchen or bathroom scales.
