NAICS Code 334519-09 Description (8-Digit)

Hydrometers are devices used to measure the specific gravity or density of liquids. The manufacturing of hydrometers involves the production of these devices, which are typically made of glass or plastic and consist of a weighted bulb at the bottom and a graduated stem. The manufacturing process involves the calibration of the hydrometer to ensure accurate readings, as well as the production of various sizes and types of hydrometers for different applications.

History

A concise historical narrative of NAICS Code 334519-09 covering global milestones and recent developments within the United States.

  • Hydrometers have been used for centuries to measure the specific gravity of liquids. The first recorded use of a hydrometer dates back to the early 16th century when Leonardo da Vinci used a device to measure the density of liquids. In the 18th century, Antoine Baumé developed a scale for hydrometers that is still used today. The hydrometer industry grew rapidly in the 19th century with the development of new materials and manufacturing techniques. In the United States, the industry saw significant growth during World War II when hydrometers were used to measure the density of aviation fuel. In recent years, the industry has seen a decline in demand due to the development of new technologies for measuring liquid density, such as digital refractometers and density meters.
