RADWAG AVK-1000 Automatic Vacuum Mass Comparator

RADWAG Balances and Scales (Poland) - RADWAG-manufactured AVK-1000 automatic vacuum mass comparator enables comparison of up to 6 artefacts of cylinder or sphere shape, and of max 1kg mass, with readability of d = 0.1 µg. A specially designed vacuum chamber makes it possible to carry out measurements in a vacuum of 10-6 mBar capacity or in atmosphere containing noble gases.

The comparator is equipped with a suspended weighing pan that eliminates eccentricity errors. AVK-1000 features larger weighing chamber that allows to convert mass unit to kilogram aliquot. Standard version of the mass comparator features thermo-hygro-barometer for testing ambient conditions with great accuracy.

The AVK-1000 vacuum mass comparator can be equipped with the LOAD LOCK system for carrying mass standards. The system enables switching or adding artefacts without changing the atmosphere inside the main chamber. With the use of a special chamber for mass standards switching the whole process is 90% shorter. The comparator is also equipped with high quality vacuum gauge.

The comparator is applied in metrological institutes where the national 1 kg mass standard is maintained and where the mass of this standard is converted into: mass standards of lower accuracy classes, derived units standards (force, pressure) and measuring equipment for mass and derived quantities.
