Hydrometer for liquids and specific gravity measurements Purpose and use: This density and specific gravity hydrometer is designed as a petroleum making tool and general liquid tester. It helps you determine the density and specific gravity of liquids during processing or testing. How to use: Pour a sample into a tall glass or plastic cylinder (not included). Place the hydrometer in the liquid and let it float. Read the scale at the liquid meniscus, leaving enough space at the for accurate measurement. Easy to read and operate: The device is straightforward to use for clear density readings, with readings taken from the floating hydrometer in the liquid. Density and reading guidance: Whether you are following a recipe or brewing your own, be sure to know the correct density for consistent results. Compatibility and applications: Suitable for home use, labs, and other occasions where liquid density or specific gravity needs to be measured. Specific gravity consideration: Ensure there is adequate headspace in the test container so the liquid does not touch the of the hydrometer during measurement. Quality assurance: Each unit has been tested to ensure accuracy and reliability. Use scenarios: Home brewing or cooking: monitor density during fermentation or formulation to achieve desired results. Laboratory testing: perform density measurements on various liquids in controlled settings. Petroleum or chemical processing: check liquid density during formulation or processing to maintain standards.
