Mechanical Balance

Mechanical balances determine the mass of an object by comparing it with known weights using the principle of lever equilibrium. They are used in laboratories for weighing samples and raw materials, as well as for quantitative analysis in the coatings and inks industry, such as measuring pigment ratios and paper grammage.
Selection
When selecting, consider the weighing range to cover common sample weights, ensure the sensitivity meets the division value requirements, check the wear level of the knife edges and the stability of the beam. The environment should avoid vibrations and air currents, and select an appropriate pan size based on the container dimensions.
