Product Details

This hydrometer is used to measure the specific gravity (relative density) for heavy liquids measuring in range from 1.000 to 2.000 in .01 divisions. 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. Great for STEM science education and classroom demonstrations. 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 a high-density liquid such as brine, milk or acid, it doesn't sink so far. Therefore, for ease of measurement, it is usual to have two separate instruments, one for heavy liquids on which the mark 1.000 is near the top of the stem, and one for light liquids on which the mark 1.000 is near the bottom.
 
Hydrometers bear other names depending on their specialized use. For instance, a Lactometer is used to check the purity of cow’s milk, Saccharometer measures the concentration of sugar in a solution, Urinometer measures specific gravity of urine, Alcoholmeter is use to indicate the alcoholic strength in liquids (also known as proof and Tralles hydrometer), Thermohydrometer measures density of petroleum products, Acidometer measures specific gravity of an acid or Antifreeze Tester determines ratio of antifreeze to water for engine cooling and freezing. These specialized hydrometers may also use a different scale of measurement. Examples are API gravity for the petroleum industry, Brix scale for fruit juice, wine and sugar industry, Plato scale for brewing or Oechsle scale for density of grape must.
