Description

A laboratory density hydrometer measures a liquid’s specific gravity or relative density (how heavy it is compared to water) by floating in it, with the reading taken where the liquid meets the stem. Key uses include quality control in petroleum (fuel blending), brewing/distilling (sugar/alcohol levels), pharmaceuticals (formulation density), food & beverage (syrups), battery testing (charge), and environmental (salinity/pollution), providing quick, cost-effective density checks for product consistency and safety.
