RADWAG-manufactured AVK-1000 automatic vacuum mass comparator is intended for national metrological  (more)institutes that transfer 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. 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. During mass standards replacement carried out without the use of the LOAD LOCK system, the air enters the main chamber of the mass comparator. After each opening of the chamber it is necessary to pump the air out in order to obtain required vacuum value. The vacuum mass comparator needs approx. 48 hours in order to obtain vacuum that ensures measurement repeatability. The LOAD LOCK is equipped with a high-efficiency pump system, the time of pumping the air out in order to enable opening of the valve of the main chamber is significantly shortened. The stabilization of the main chamber after replacing/adding the mass standard and closing the valve connecting the main chamber and the LOAD LOCK system takes 5 hours. The high-quality vacuum gauges enable monitoring and comparing the vacuum value in order to determine the moment when opening the valve again and replacing the mass standard is available. A specially designed viewfinder enables monitoring of the process. The LOAD LOCK enables switching objects of dimensions adapted to the AVK-1000 mass comparator: cylindrical mass standards of 22-95 mm diameter and silicone spheres of 40-100 mm diameter. Supplementing the AVK-1000 vacuum mass comparator with LOAD LOCK system significantly improves the comparison performance.

The newest line of Radwag Mass Comparators enables adjusting mass standards and weights according to (more) the OIML recommendations (R-111) from 5 kg to 20kg for E1 class and lower. Mass comparators are used both for ensuring traceability of mass measurements, and verification of weights in accordance with the principles of legal metrology. RADWAG Mass Comparators have gained recognition among Accredited Calibration Laboratories in many countries. Mass comparator APP 5Y.KO series comprises two components. One of them holds the electronic module, and the other precise mechanical measuring system. High measuring accuracy is guaranteed by semi-automatic adjustment system with external mass standard. The weighing pan made of aluminium is covered with cork layer and features centering holders for the weights. The APP 5Y.KO series features an intuitive menu supporting a user in instrument operation. Correct operation of the mass comparator requires applying a special anti-draft shield which comes standard with the instrument.

RS 232 cable: Balance - computer. Standard cable length: 1.7 m. Compatible with: - Scales with PUE C (more)315 terminal - PUE C315 terminal

The 21 CFR Part 11 Compliance Module is a solution especially useful for those users who are obliged (more) to conform to provisions of 21 CFR Part 11 and EU GMP Part 4, Annex 11 regulations. These two documents determine the rules for using electronic records and signatures. Data protection is guaranteed by: advanced password settings, control of logging correctness, various permission levels, data management access, backup, electronic signature, time-defined automatic logout, modification record to Audit Trail file. The module includes "Audit Trail". Audit Trail is a kind of a log where all modifications of balance settings, changes in database records and user activity are recorded. Audit Trail, for example, keeps record of previous and new modifications in databases and informs by whom and when they were introduced. This log allows the administrator to track and find out who logged in, when, who signed a document or who used invalid password. The Audit Trail Reader freeware allows users, upon connection with a balance, to display Audit Trail log and manage it by generating reports of various formats: pdf, xls, csv, html.

One of them holds the electronic module, and the other precise mechanical measuring system. The WAY 5Y.KO series comes standard with an aesthetic, large weighing chamber with glass anti-draft shield. All elements of the weighing chamber are manufactured from glass or metal to minimize the influence of electrostatic charges on weighing result. Mass comparator WAY 5Y.KO series features an intuitive menu supporting a user while operating the instrument.

The offered instrument / system is fully functional tested and ready to use. FURTHER DETAILS TO FOLL (more)OW
