Individually serialized hydrometers from Grainger help determine standard parameters and a variety of special applications for a wide range of liquids. An API hydrometer can measure the specific gravity of petroleum products, and a sugar or Brix hydrometer can determine sucrose content. Certified instruments include a calibration report with corrections to 1/10 of the smallest division. Browse Grainger’s selection of high-quality hydrometers to find the instrument that can fit your application.Close
