Density meters are instruments that measure the density of a sample liquid or gas. Digital density meters are used in the pharmaceutical, petroleum, chemical, and food and beverage industries for quality control and in research and development. Density meters work by measuring the oscillation of a glass tube that contains the sample. There are digital density meters that can measure specific gravity and refraction index as well as the density of a sample. There are density meters available that are portable or benchtop models, that can measure liquid, gas, or both, and have a built-in thermostat or need a water bath to maintain temperature. Some other variations include sample volume needed, speed of testing, and the ability to take and store images.
