Measurement in a vacuum of 10(-6) mBar Suspended weighing pan for elimination of eccentricity errors LOAD LOCK – Mass standard transfer system AVK-1000 – Automatic Vacuum Mass Comparator COMPARISON IN VACUUM WITH THE HIGHEST ACCURAC

Comparison in vacuum or noble gases RADWAG-manufactured AVK-1000 automatic vacuum mass comparator is intended mainly for national metrological institutes that transport and maintain the national reference mass standard of 1 kg. The comparator is intended for weighing mass standards and silicone spheres of 100 mm diameter. It enables comparison of up to 6 artefacts of maximum 1kg mass. The readability of the process is 0.1 µg. The comparator is placed inside a specially designed vacuum chamber which enables carrying out measurements in a vacuum of 10(-6) mBar capacity or in atmosphere containing...

Resolution of 10 billion units Repeatability of 0.5 μg Effective and Excellent Measurement Resolution of 10 billion units plus elimination of human error and other external factors due to the use of vacuum chamber effectively prevent any potential errors that may occur during the measurement. Used chamber enables comparison in vacuum of maximum 10(-6) mBar or in noble gases such as argon. Mass Standard Maintenance The AVK-1000 automatic vacuum mass comparator is mainly intended for national metrological institutes that transport and maintain the national reference mass standard of 1 kg. Excellent...

The mass comparator features second, integrated weighing pan. It is used to compensate mass during calibration of mass standards lighter than 1 kg. The main chamber of mass comparator is equipped with 8 flanges (DN 40 ISO KF) for connecting devices such as vacuum gauge, solenoid valves, CO2 sensors etc. LOAD LOCK chamber features 2 such flanges.
