How to Test a Hygrometer. If you're a cigar aficionado, you need a hygrometer to make sure you're storing your wares at the correct humidity. A hygrometer is an instrument that is used to measure humidity in cigar humidors as well as greenhouses, incubators, museums, and more.
A hydrometer or areometer is an instrument that measures the specific gravity (relative density) of liquidsâthe ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. 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.
