In our product portfolio we offer, amongst others, areometers by the producers Gering and Schneider after Twaddle, Baumé, Casagrande and more. Areometers are measurement devices to determine the denseness and weight of liquids. Areometers function with the Archimedian Principle: A solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced by the submerged part of the solid suspended.
