hydrometer

A glass hydrometer is an essential tool used to measure the specific gravity or density of liquids. Typically made of glass, this delicate instrument consists of a sealed tube filled with a weighted bulb at one end. When immersed in a liquid, the hydrometer floats at a level corresponding to the liquid's density, allowing users to read the specific gravity on a calibrated scale. Commonly utilized in various industries, including brewing, winemaking, and laboratory settings, glass hydrometers provide accurate measurements that are crucial for quality control and formulation processes. Their transparency allows for easy reading, while the glass construction ensures durability and resistance to chemical reactions. By understanding the specific gravity of a liquid, professionals can make informed decisions that enhance product quality and performance.
