What is the advantage of a digital density specific gravity meter vs. a glass hydrometer?

Our digital handheld density meter is fast and accurate, with measurements results within seconds and an accuracy of 0.001 g/cm3. The built-in electric sampling pump allows for controlled sampling and rinsing at the press of a button, avoiding user dependent sampling workflows. Digitally supported workflows include entering sample entry with a barcode reader or RFID reader, QC with automatic passed/failed information and export of data to a printer or a PC software, reduce transcription errors and save time. In summary, a digital density specific gravity meter offers faster, more accurate and operator independent measurement results.

 

Can a digital density specific gravity meter measure in other units than density and specific gravity?

Yes, in addition to density and specific gravity, our digital density specific gravity meter has built-in conversion tables for Ethanol (Alcohol), Brix, API, Baumé, H2SO4, Plato, Proof (US and IP) and user-defined concentration.

 

What about temperature dependency of the density of samples?

Our portable specific gravity meters offer built-in temperature compensation to measure the sample at any temperature between 0°C and 50°C (32°F to 122°F) and calculate the density at the required temperature (e.g. 20°). The benchtop specific gravity meters have a built-in Peltier thermostat to bring the sample to the selected temperature.

 

What is the technology used in a digital density meter?

Digital density meters use the oscillation tube technology to measure very accurately the density of a sample in a short time. Only a small amount of sample is required to fill the measuring cell (approx. 2 mL).

 

What is the difference between specific gravity and density?

Density is defined as the mass of a substance divided by it’s volume, and is expressed in g/cm3, kg/m3 or lb/ft3.
