RADWAG AS 220.R2 PLUS Analytical Balance

AS 220.R2 PLUS Analytical Balance | High-Precision Analytical Weighing Instrument from the SYNERGY LAB Line

The AS 220.R2 PLUS analytical balance is part of the AS R2 PLUS series, a standard range of high-precision weighing instruments developed under the SYNERGY LAB line. This model incorporates advanced structural and system solutions that ensure exceptional reliability, precision, and measurement accuracy, while facilitating user-friendly, daily laboratory operation.

Ergonomic Mechanical Design

The AS R2 PLUS features an enlarged weighing chamber, improving usability and convenience. The wide open-door clearance allows for easy access to the weighing pan, making it possible to use laboratory glassware of various sizes.

A newly designed aluminium base guarantees structural rigidity and ensures the stability of the weighing system during operation.

Key design features include:

• Dual-CLICK System: Enables tool-free assembly and disassembly of the weighing chamber, significantly reducing maintenance time.
• Rimless Guide Rails: Specially engineered guides for the chamber panes prevent the accumulation of debris and simplify cleaning.
• Durability: The use of innovative construction materials and methods improves both the durability and long-term reliability of the balance.

Levelling System

The balance is equipped with an ergonomic front-mounted levelling device, allowing the user to easily monitor and adjust the level of the instrument. The system has been streamlined with only two adjustable supporting points, simplifying the levelling procedure and reducing the potential for error.

User Interface and Intuitive Operation

The AS R2 PLUS is designed for efficient and intuitive operation through a high-contrast LCD display and easily accessible function keys.

Key interface features include:

• LCD Display: Clearly presents measurement data, operational status, and supplementary information such as tare values or product names.
• Status Bar: Displays additional real-time messages and alerts.
• Bar Graph Display: Visualizes mass measurement changes in real-time.
• Dedicated Keys:
  • Database: Direct access to stored databases.
  • Function: Shortcut to core operating features.
  • F1–F4: Programmable function and navigation keys.

Pictograms indicate active operation modes (e.g., weighing, service, or PC connection) for efficient workflow management.

Internal Adjustment Mechanism

The modernised internal adjustment system ensures high accuracy even under unfavourable environmental conditions, reducing measurement drift and maintaining calibration integrity over time.

Data Protection and Security

The AS R2 PLUS balance incorporates robust data security features:

• Access Control: Secure data access is restricted via a login system. An administrator role allows configuration and control of user permissions.
• ALIBI Memory: Integrated ALIBI memory ensures long-term data storage and traceability, with a capacity for up to 100,000 weighing records. This system guarantees uninterrupted data collection and secure archival of historical records.

Integrated Database System

The balance supports a comprehensive information management system based on five separate databases, enhancing multi-user functionality and enabling organised record-keeping for multiple products and weighing tasks:

• Operators: Up to 10 users
• Products: Up to 1,000 product entries
• Weighings: Up to 5,000 records
• Tares: Up to 100 values
• ALIBI Memory: Up to 100,000 entries

This structured system facilitates data retrieval, result analysis, and workflow automation in laboratory environments.

Communication Interfaces

The AS R2 PLUS supports a range of communication options for external data management and device integration:

• USB-A
• USB-B
• RS 232
• Wi-Fi® (optional)

These interfaces enable easy connection to laboratory information systems (LIS), external computers, and other data processing devices.

Optional Feature: Under-Pan Weighing

All AS R2 PLUS balances purchased after 15 February 2023 are compatible with under-pan weighing, which allows the measurement of suspended samples. This feature can be enabled post-purchase by ordering a dedicated under-pan hook, making the balance highly adaptable for specialised applications.
