Hydrostatic Balance

The hydrostatic balance measures the weight difference of an object in air and water based on Archimedes' principle to calculate density and volume. It is used to detect the density, porosity, and compositional uniformity of solid materials, commonly applied in quality control for materials such as plastics, rubber, and ceramics.
Selection
When selecting a hydrostatic balance, it is essential to consider the weighing range and accuracy to match the sample characteristics, while also paying attention to temperature stability and corrosion resistance. The balance should include calibration functions and compatible suspension devices, with a clear and user-friendly interface to facilitate daily testing operations.
