Hydrometers for Specific Gravity
Our hydrometers for specific gravity deliver precise density measurements of liquids in accordance with ASTM E100-19. Available with or without an integrated thermometer, they are widely used in laboratories, in quality assurance and across industrial inspection processes wherever the density of a liquid must be measured in a standard-compliant and reproducible way.
Hydrometers for Specific Gravity
Our hydrometers for specific gravity deliver precise density measurements of liquids in accordance with ASTM E100-19. Available with or without an integrated thermometer, they are widely used in laboratories, in quality assurance and across industrial inspection processes wherever the density of a liquid must be measured in a standard-compliant and reproducible way.
Applications of density measurement with hydrometers
The density measurement of liquids is one of the most fundamental tests in research, production and quality control. A hydrometer used to measure specific gravity delivers reliable readings without electronic instruments and without a power supply. Typical applications include the incoming inspection of raw materials in the chemical and pharmaceutical industries, the testing of solutions, emulsions and alkaline media in mineral oil and chemical analysis, as well as quality assurance in food and beverage technology, for example for sugar, salt or alcohol solutions. In research and laboratory analysis, hydrometers also serve as reference instruments for comparative measurements and validations.
Designs and technical features of our hydrometers
To suit every measuring task, we manufacture several designs of hydrometers for specific gravity measurement. The range-finder hydrometer is ideal for the quick initial assessment of unknown liquids over a wide measuring range, while our ASTM specific gravity hydrometer is built to ASTM E100-19 for standardised testing and internationally comparable results. For media with high density up to 2.000 sp/gr, we offer dedicated hydrometers for heavy liquids. All versions reach an accuracy of ±0.0005 sp/gr at a reference temperature of 60/60 °F and can be supplied with an integrated thermometer on request, so density and temperature can be captured in a single step.
Order your hydrometer for specific gravity directly from the manufacturer
If you are looking for a precise hydrometer for specific gravity for laboratory work, quality assurance or industrial inspection, you have come to the right place. As an experienced manufacturer, we offer high-quality standard versions built to ASTM E100-19 as well as individually produced models for specific applications. On request, every hydrometer is supplied with a works calibration certificate or a traceable DAkkS calibration certificate, so you can fully document the traceability of your measurement results to the relevant standard.
Please get in touch for individual advice. Our measurement technology specialists will help you select the right instrument for your requirements.
Unique all-round service by our Ludwig Schneider Messtechnik GmbH
Our DAkkS calibration laboratory is accredited according to DIN EN ISO/IEC 17025:2018 for the measurands temperature and density.
