The AGV-2/20 automatic comparator determines density and volume of mass standards of class E1 and lower in accordance with OIML R111. It is characterized by the highest accuracy and measurement stability ranging between 1 kg to 20 kg.
The comparator features specially designed feeder to load and unload the magazine with mass standards. The device is equipped with an additional circulator eliminating air bubbles and a top-class liquid temperature sensor of 0.001 ˚C accuracy. A weighing pan suspended on wires eliminates the eccentricity and minimizes the influence of liquid surface tension.
Dedicated software enables to determine mass standards density and calculate uncertainty using A method according to OIML R111. It also allows to determine (verify) liquid density.
