The AS 220.R2 PLUS Analytical Balance from RADWAG’s SYNERGY LAB series is a high-precision weighing instrument designed for analytical laboratories, research institutions, and quality control environments.
With a maximum capacity of 220 g and readability of 0.1 mg, the balance delivers highly accurate and repeatable measurements. Modern design features, advanced data management, and an intuitive user interface ensure reliable performance and efficient daily operation.
The spacious weighing chamber, ergonomic construction, and integrated internal automatic adjustment system allow the balance to maintain precision even in demanding laboratory conditions.
The integrated internal calibration system ensures high measurement accuracy even under unstable environmental conditions.
Secure login access allows administrators to control user permissions.
Stores up to 100,000 weighing records for secure traceability.
The balance includes five internal databases:
Database | Capacity |
Operators | Up to 10 users |
Products | Up to 1000 products |
Weighings | Up to 5000 records |
Tares | Up to 100 |
ALIBI memory | Up to 100,000 weighings |
Multiple communication options allow integration with laboratory information systems:
Barcode scanners can connect through the RS-232 interface.
Under-Pan Weighing
Balances manufactured after 15 February 2023 support optional under-pan weighing with a dedicated hook.

Repeatability is expressed as a standard deviation from 10 weighing cycles.
Stabilization time depends on the ambient conditions and the dynamics of weighing pan loading; specified for FAST profile.
* Power consumption depends on the terminal configurations as well as the number and type of external devices connected.
1 Barcode scanners, available as weighing instrument accessory, communicate with the instrument via RS232 interface exclusively.
