The AS.R series represents a new standard level for analytical balances. It features modern, readable LCD display which allows a clearer presentation of the weighing result. The display has a new text information line presenting additional messages and data, e.g. product name or tare value.

Additionally, the new R series balance uses great number of pictograms to signal the active working mode, connection with the Internet, the battery charge level, balance service functions. Measuring units number has also been increased.

The balance precision and the measurement accuracy is assured by automatic internal adjustment, which analyses temperature changes and time flow.

AS.R series balance features several communication interfaces: 2 x RS 232, type A USB, type B USB and optional Wireless Connection.

The balance may cooperate with computer by means of USB interface supposing a supplementary software has been installed (respective driver). The said driver may be downloaded from RADWAG website – SOFTWARE link or SUPPORT section.

The housing is made of plastic, and the pan is made of stainless steel.

In new AS.R series balance the information system is based on 5 databases, which allows several users to work with several product databases, and the registered weighing results can be subject to further analysis.


  • The data is registered in 5 databases:
    • users (up to 10users),
    • products (up to 1000 products),
    • Weighings (up to 5000 weighings),
    • tares (up to 100 tares),
    • ALIBI memory (up to 100 000 weighments).
    • There is two-direction data exchange within the system thanks to a quick USB interface. New balance allows to import and export databases using USB pen drives.
  • Interfaces:
    • - 2×RS 232
    • - USB-A
