Measuring Alcohol Concentration for Proof by measuring the Density of Alcohol. Alcohol Concentration Determination Introduction Pycnometers, hydrometers, and digital density meters are officially recognized methods for the determination / measuring alcohol (ethanol) concentration for quality control and to insure proper product labeling for declaration of alcohol content (Proof) for the payment of tax. In the
This was installed very efficiently … and it is working to our satisfaction…
I would highly recommend the DDM 2910 Automatic Density Meter and Rudolph Research Analytical to anyone…
The density meter is working out great! We just ran about 16 lots on it and it is so much easier/faster than the pycnometer…
Since the system was installed in September, we have analyzed 3000 samples and have not had a single problem…
I would definitely recommend your instrumentation to anyone I know because it is excellent instrumentation and awesome technical support always.

Density Meter Application Report Concentration Determinations using the Rudolph Research Analytical DDM 2911 Density Meter Introduction From purely an intuitive approach, it is easy to understand how a density meter can determine concentrations. If you were to measure the density of a pure water sample, you would find its density to be 0.9982 g/cm 3
