Hydrometers

Durac specific gravity hydrometers measure the relative density of liquids compared to water in food & beverage, chemical, pharmacology, transportation and refrigeration industries. They have lead free ballast and glass construction for corrosion resistance and durability. Raptor Supplies also offers soil hydrometersto test the distribution of soil particle sizes for analysis of soil quality. Choose from a wide array of these ASTM certified hydrometers for measuring specific gravity ranging from 0.75 to 2 at a standardised temperature of 60 / 68 degrees F.

Durac hydrometers have convenient built-in thermometers to measure the relative density i.e. the specific gravity of petroleum and oil-related products in temperatures up to 158 degrees F. They feature lead-free ballast having glass construction for visualising accurate measurements and are ideal for chemical, food & beverage, transportation, pharmacology & refrigeration applications. These individually serialised hydrometers have waterproof temperature probes and contain mercury-free, organic liquid fill for indicating temperatures. Choose from a wide range of these hydrometers, available in API ASTM, liter, salt brine, Baume, Brix, humidity and NaCl scales for various types of measurements.
