Automatic vacuum mass comparator AVK-1000 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.
