Digital Density Specific Gravity Meter

Digital Density Specific Gravity Meter

Fully Automatic Density Meter

A digital density specific gravity meter is a device designed for measuring the specific gravity of liquids in various industries such as pharmaceutical, food and beverage, chemical, and more. There are two types of density specific gravity meters, portable and benchtop models. A portable density specific gravity meter offers temperature compensation to report the specific gravity or the density at a selected temperature, while the benchtop models have a built-in Peltier thermostat to bring the sample to the selected temperature.

FAQs

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.
