Our density measuring devices are based on the principle of buoyancy (discovered over 2,000 years ago by Archimedes). With our flotation scales and areometers, we can determine the density of liquids down to a difference of 0.001 (one thousandth) of a gram in weight. This is done in an environmentally-friendly way without electrical energy sources, purely mechanically and accurately due to the relevant design features. The concentration of anti-freeze for example can be determined from the density. From this concentration, the anti-freeze properties are derived and displayed on the scale. Only this above accuracy enables the determination of the required anti-freeze reliability of water/coolant mixtures. Our measuring devices meet these quality requirements, as well as the robustness required for workshop use.
