XA 4Y M A Microbalances (with automatic door)

Category Laboratory Balances
Manufacturer Radwag
Country of manufacture Poland

Feature modern design that enables high accuracy and fast measurements.

They are equipped with reliable measuring system housed within a tight casing. With this feature, the balance provides accuracy and fast measurement for almost any laboratory conditions. The electronic part of the balance features modern hardware and software architecture. Integrated software, Windows Embedded Compact 7, Flash memory, Double Hardware System guarantee speed and reliability of collecting and processing information. 4Y.M series is equipped with 5.7" LCD colour touch screen which improves weighing instruments operation and presenting measurements results. Complex databases enable to register, print and export measurements. The weighing instrument system supports 13 languages. 4Y.M microbalance is an optimized modern tool equipped with an automatic levelling control system (LevelSENSING). 

Customization option is based on individual operators’ profiles and permissions levels that limit the access to the weighing instrument's menu. Programmable proximity sensors offer wide range of possibilities: zeroing, taring, printing and more.

Numerous functions, such as differential weighing, enable multi-step mass control of the same sample subjected to different processes.

The software security system and the ability to document the process using printouts (standard/non-standard) ensures compliance of the weighing instruments with GLP/GMP systems in almost every area (pharmacy, petrochemistry, environment protection and many others).

Integrated Antistatic Ionizer: The antistatic ionizer, with which XA 4Y.M.A microbalance is equipped, neutralizes electric charges inside the weighing chamber upon placing the sample in it.

New Door Opening Automatics: The innovative weighing chamber system for door opening and closing guarantees smooth and quiet door movement, and eliminates vibrations that may disturb the measurement.

CAUTION: In order to carry out the weighing process by means of microbalances and ultra-microbalances correctly, it is necessary to prepare the workstation and to operate the device as required. Please follow usage and installation guidelines
