The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely, The point at which the surface of the liquid touches the stem of the hydrometer correlates to specific gravity., Hydrometers usually contain a scale inside the stem, so that the person using it can read specific gravity., Hydrometer for Measuring Specific Gravity Heavy Liquid density (Measurement Range, 1000-2000), Pack of 4
