Description

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.

AVK-1000 vacuum mass comparator has been made for Central Office of Measures in Warsaw.

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.

Overview

Maximum capacity [Max]: 1002g

Readability [d]: 0,1µg

 We manufactured AVK-1000 automatic vacuum mass comparator is intended 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 prototypes of max 1kg mass. The repeatability of the process is of 0.3 µg and readability of d = 0.1 µg.

A specially designed vacuum chamber enables carrying out measurements in a vacuum of 10-6 mBar capacity or in atmosphere containing noble gases.

AVK-1000 is equipped with suspended weighing pan that eliminates eccentricity errors.

Standard version of the mass comparator features thermo-hygro-barometer for testing ambient conditions with great accuracy: pressure of 0.001hPa, humidity of 0.01% and temperature of 0.001 °C.
The comparator is also equipped with high quality vacuum gauge.
