The use of density meters is very wide. More than water, to determine the density of various acids, alkalis, aqueous salt solution, such as acid sulfuric acid, nitric acid, hydrochloric acid and some inorganic acids or organic acids.
Light than water to determine the methanol, ethanol, ether and other solutions, and gasoline, kerosene, vegetable oil, petroleum ether and other liquid density.
For laboratories, laboratories in the determination of liquid density, the use of second-class standard density meter is more appropriate.
Common specifications: (0.6-0.7-0.8-0.9-1.0), (1.0-1.1-1.2-1.3), (1.3-1.4.), (1.4-1.5), (1.5-1.6), (1.6-1.7-1.8 -1.9-2.0).
