Glass Hydrometer Aerometer Set of 3 Density 0.90-2.10 1.75-1.80 1.80-2.00

Glass Hydrometer Aerometer Set of 3 Density 0.90-2.10 1.75-1.80 1.80-2.00

This lot of three glass hydrometers (aerometers) covers three distinct specific gravity / liquid density ranges: 0.90 to 2.10, 1.80 to 2.00, and 1.750 to 1.800. Each instrument is a traditional glass float-type hydrometer with a weighted bulb end and a long graduated stem carrying a printed paper scale, used to measure the density of liquids by the depth to which the instrument sinks when floated in the sample.

Applications

Glass hydrometers of this type are standard tools in chemistry labs, quality control, and industrial process settings for measuring the specific gravity of liquids — acids, bases, electrolytes, brines, plating solutions, battery electrolyte, and other chemical solutions. The overlapping density ranges in this set make it useful for dense liquids such as sulfuric acid solutions, concentrated brines, and heavy industrial fluids. Hydrometers in the 1.75–2.10 range are commonly used in battery electrolyte testing, metal finishing/plating baths, and chemical manufacturing where concentrated acid or salt solutions are routinely monitored. The broader 0.90–2.10 instrument provides a single-instrument overview across a wide range, while the two narrower-range instruments allow finer resolution readings in the 1.75–2.00 zone.
