Physical Balance

The physical balance operates on the principle of lever equilibrium, determining the mass of an object by comparing the torque generated between the measured object and standard weights on both ends of an equal-arm lever. It is used in laboratories for weighing solid powders or granular samples, and in the coatings industry, it can measure pigment ratios and control the amount of filler added during ink production.
Selection
When selecting, consider that the weighing range covers the sample weight, and the reading accuracy meets process requirements. Pay attention to the corrosion resistance of the balance material to suit the laboratory environment, and check the leveling adjustment device to ensure measurement stability. Verify the validity of the calibration certificate and observe the integrity of the draft shield to minimize airflow interference.
