We have the tools for you to measure density and specific gravity. A density meter provides a way to measure the gravity of substances. A hydrometers offer a simple, yet accurate way to measure the relative density or specific gravity of most any substance. Our standard hydrometers are available in ranges both lighter and heavier than water, and in either the standard specific gravity scale or in degrees Baumé. Another density meter family includes specific gravity cups for weight per gallon measurements, pycnometers for viscous and semifluids, Gay-Lussac bottles, and digital density/specific gravity meters.
