Specific Gravity Hydrometers for Liquids Lighter than Water

Specific gravity hydrometers measure the ratio of the density of a sample compared to the density of pure water at the same temperature. The specified temperature for these types of hydrometers is 60/60 °F (15.6/15.6 °C). These hydrometers are designed for liquids with a specific gravity < 1.000 g/mL. DH006.501 is ideal for monitoring Liquid Petroleum Gas. Select from plain or combined form (with thermometer) models in a variety of lengths.
