Name: AVK 1000.5Y Automatic Vacuum Mass Comparator equipped with pumps
Brand: RADWAG
SKU: WL-417-0003

Discover an advanced metrology solution with the AVK 1000.5Y automatic vacuum mass comparator. This innovative piece of equipment is designed for precise mass comparison under vacuum conditions of 10^-6 mbar, eliminating the influence of air on measurements. Equipped with state-of-the-art pumps, it ensures efficient air extraction, thereby speeding up the measurement process and increasing the accuracy of the results.

Vacuum Levels of up to 10^-6 mbar? Not a Problem for us!

The comparator is equipped with a pumping system that consists of 2 pumps: a pre-pump and a turbomolecular pump, as well as a high-performance vacuum gauge. Pre-pumps and turbomolecular pumps work together to ensure vacuum continuity and stability in systems where different vacuum qualities are required. The pre-pump lowers the pressure to a level where the turbomolecular pump can operate effectively, allowing the desired vacuum to be achieved throughout the system.

The pre-pump

It works on the principle of mechanical suction of gases and their compression. Its main task is to reduce the pressure to a level where the turbomolecular pumps can operate effectively. These pumps are capable of producing a vacuum of 10^-3 to 10^-4 hPa.

The turbomolecular pump

It uses impellers rotating at very high speeds to accelerate gas molecules. These molecules are “pulled” into the pump by the action of centrifugal force. It allows much lower pressures (up to 10^-10 hPa) than pre-pumps.

Convenience and Full Control over the Process

The high-performance vacuum gauges used in the device allow the vacuum values to be monitored and compared in order to determine when the valve can be opened and the gauge replaced. A specially made viewfinder allows the entire process to be monitored. During mass standards exchange, air enters directly into the main chamber of the comparator. Each time it is opened, the air must be pumped out to the correct vacuum value. The vacuum comparator requires approximately 48 hours to reach a vacuum value that ensures repeatability of measurements.

What Additional Capabilities Does the AVK-1000.5Y Have?

Automatic calibration mechanism

with the possibility of replacing the calibration mass standard with a mass standard of lesser mass to check the sensitivity of the comparator.

Comparison capability in a noble gas atmosphere

A key element in the design of the comparator is a specially designed vacuum chamber that allows measurements to be carried out under vacuum conditions of 10^-6 mbar or in a noble gas atmosphere. This enables stable and repeatable results even under the most demanding conditions.

6-position mass standard magazine

It allows automatic exchange of mass standards during the measuring process.

Self-centring weighing pan

This is a component of the comparator which ensures that the mass standard is always in the centre of the pan, regardless of its initial position. It eliminates the problem of eccentricity.

Thermohygrobarometer

It exercises comprehensive control over the precision measurement environment, increasing accuracy and improving repeatability.

Anti-vibration table with granite top

It eliminates the effects of ambient vibration to keep measurements stable during weighing. You receive the table together with the comparator.

Intuitive control

The AVK 1000.5Y comparator is not only efficient, but also intuitive to use thanks to the 10’’ touchscreen display, which allows easy management of the device’s functions. In addition, security of use is ensured through a variety of authentication methods, including passwords, RFID tags*, fingerprint readers and facial recognition mechanisms.
