AS 120.R2 PLUS Analytical Balance

Balance of the AS R2 PLUS series is a standard analytical weighing device of the SYNERGY LAB line. The AS R2 PLUS is exceptional due to a range of modern constructional and system solutions that guarantee reliability, precision and accuracy of measurement, and make everyday operation easy.

Ergonomic Mechanical Design

The latest AS R2 PLUS analytical balance features spacious weighing chamber, and the open-door clearance facilitates easy access to the weighing pan. With this it is possible to use laboratory glassware of various sizes. New aluminium base is a guarantee for weighing system stability.

Dual-CLICK system allows tool-free assembly and disassembly of the weighing chamber, and a special design of guides for weighing chamber panes (no rims) makes keeping the device clean convenient.

Innovative construction solutions increase balance durability and reliability in long-term operation.

Levelling System

Standard AS R2 PLUS balances are equipped with a levelling device located at the front of the weighing chamber, which facilitates level control. Levelling operation is now simplified and easier due to the reduced quantity of adjustable supporting points (2 points).

Intuitive Operation

Balances are equipped with LCD display ensuring clear presentation of the weighing result. Direct access to functions and databases is possible via the following keys:

Database – direct access to databases,
Function – direct access to basic functions,
F1-F4 – programmable function keys and menu navigation keys.

AS R2 PLUS analytical balances signal operated working mode, computer connection, weighing and service functions via pictograms. The quantity of displayed weighing units is also expanded. Dedicated status bar enables display of additional messages, e.g. product name, tare value. Real-time mass measurement is presented using bar graph.

Internal Adjustment

Modernized internal adjustment system guarantees accurate indications in extremely unfavourable conditions.

Data Protection

Access to valuable information is possible after logging. The administrator manages the data access configuration.

ALIBI Memory

Data safety is ensured by the ALIBI memory integrated into AS R2 PLUS balances, which enables record of up to 100 000 weighings. ALIBI guarantees continuity of data collection over a long period of time.

Databases

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:

operators (up to 10 users),
products (up to 1000 products),
weighings (up to 5000 weighings),
tares (up to 100 tares),
ALIBI memory (up to 100 000 weighings).

Communication Interfaces

The functionality of AS R2 PLUS balances can be expanded using the following communication interfaces: USB-A, USB-B, RS 232, Wi-Fi^® (option).

Additional option:

Under-pan weighing

Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook.
