Ultra-High Precision Analytical Balance with Internal Calibration and Advanced Data Management

The Radwag AS 120.R2 PLUS Analytical Balance is a high-performance analytical weighing instrument designed for ultra-precise laboratory measurements with 0.01 mg readability and 120 g capacity. Part of the SYNERGY LAB product line, the AS R2 PLUS series combines advanced mechanical design with intelligent data management and automation features to ensure maximum measurement accuracy, reliability, and ease of operation.

The spacious weighing chamber and ergonomic open-door design provide convenient access to the weighing pan, allowing the use of laboratory glassware of various sizes. A new aluminum base construction enhances weighing stability, while the Dual-CLICK system enables tool-free assembly and disassembly of the weighing chamber for easy cleaning and maintenance.

The balance includes automatic internal adjustment, which compensates for environmental changes such as temperature fluctuations to maintain precise measurement results. Additionally, the antistatic coating on the weighing chamber glass reduces electrostatic interference, improving weighing accuracy for ultra-light samples.

Equipped with multiple communication interfaces including RS232, USB, Ethernet, and optional Wi-Fi, the AS 120.R2 PLUS easily integrates with laboratory information systems, printers, and computers.
