Optical Balance

Optical balances magnify and display minute mass changes through optical projection, utilizing the principle of lever balance to measure the mass of substances. They are used in laboratories to weigh samples, raw materials, and finished products, control formulation ratios in the coatings and inks industry, and detect material density in the plastics and papermaking sectors.
Selection
When selecting, consider that the weighing range covers the weight of daily samples, and the division value meets the requirements of weighing accuracy. Observe the clarity of the optical projection and check for wear on the knife edges. Choose an appropriate size based on the usage environment, and ensure the leveling adjustment device is sensitive and stable.
