Product Details

This light liquids hydrometer is useful for measuring the specific gravity (relative density) of liquids using the concept of buoyancy. It is perfect for general industrial purposes and classroom demonstrations. Great for STEM science education.

This hydrometer is used to measure the specific gravity (relative density) for light liquids measuring in range from .70 to 1.00 in .01 increments. The hydrometer is made of a chemically-resistant glass and consists of a cylinder shaped stem and a bulb weighted with a substance to make it float upright. The overall hydrometer length is approximately 30 cm. Includes plastic storage tube.

The hydrometer requires a hydrometer jar (not included). The hydrometer is designed to be placed into the liquid filled jar, and the point at which the surface of the liquid touches the stem correlates to the specific gravity.

When a hydrometer is placed in low-density liquid such as kerosene, gasoline or alcohol, the hydrometer will sink deeper. When a hydrometer is placed in high-density liquid such as brine, milk or acid, it doesn't sink so far.

Hydrometers for a more specialized use might bear other specific names depending on their intended use. For instance, a Lactometer is used to check the purity of cow’s milk, Saccharometer measures the concentration of sugar in a solution, and an Alcoholmeter indicates the alcoholic strength in liquids (also known as proof). These specialized hydrometers may also use a different scale of measurement.
