What is a highdrometer?

Answer 1

A hydrometer is an instrument used to measure the density or specific gravity of liquids. It typically consists of a sealed glass tube with a weighted bottom that allows it to float upright in the liquid being tested. The level to which the hydrometer sinks indicates the liquid's density, which can be useful in various applications, such as brewing, winemaking, and measuring battery electrolyte strength. Hydrometers come in various types and scales, depending on the specific measurement needs.
