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.

Moisture analyzer is a laboratory measuring instrument intended to determine relative humidity for s (more)mall samples of different materials. MA.R series redefines moisture analyzers standards. The MA.R series This series has been equipped with brand new readable LCD display providing an extra text line for information such as supplementary messages and data, e.g. product name or tare value. The moisture analyzer, using respective pictograms, signalizes currently activated mode, computer connection and functions, both balance and service ones. The MA.R series is enriched with various interfaces: RS232, USB type A, USB type B and Wi-Fi. The moisture analyzer is housed in a plastic casing. Databases: Information system of R series moisture analyzers is based on 6 databases, allowing many operators to operate product database comprising many samples. Collected measurements may be subjected to subsequent analysis. Collected data is registered in 6 databases: Users (up to 10 users) Products (up to 1000 products) Weighings (up to 1000 weighings) Tares (up to 100 tares) Programs (up to 100 drying programs) Drying process reports (up to 1000 reports) The results The results obtained using the moisture analyzer (the final result of the drying process): % M – the mass loss in %; displays the mass change recorded during the drying process, expressed as a percentage, % D – the dry mass obtained during the drying process, expressed as a percentage; the result is the portion of the sample that remains on the weighing pan after the moisture has evaporated, % R – the ratio of moisture content to dry mass, obtained during the drying process, expressed as a percentage; the result is the portion of the sample that evaporated during the drying process, g – the sample mass after drying. Exchange of information within the system is performed by means of USB port on bi-directional basis. It is possible to import and export databases using memory sticks. Direct access to information It is possible to access functions and databases directly, using keyboard soft keys. Database – access to databases Function – access to basic functions F1 and F2 – programmable function keys and menu navigation keys Reports – access to database of drying process reports Profile – access to parameters settings Sample – access to products database
