Description

A&D Scale PN BM-252

A&D Scale PN BM-252 is a professional semi-micro analytical balance with internal calibration and a built-in fanless ionizer, designed for ultra-precise weighing in laboratories, pharmaceutical facilities, research institutions, chemical analysis, quality control, cannabis testing, environmental analysis, manufacturing, and other demanding scientific applications. The BM-252 features a 250 g maximum capacity with an exceptionally fine 0.00001 g (0.01 mg) readability, providing significantly greater resolution than standard 0.1 mg analytical balances while retaining the capacity needed for larger samples and weighing vessels.

A major advantage of the A&D BM-252 is its built-in fanless ionizer, which helps neutralize static electricity that can interfere with semi-micro weighing. Electrostatic charges on powders, plastics, filters, containers, pharmaceutical ingredients, films, and other samples can cause unstable readings and measurement errors. The integrated ionizer allows operators to reduce static interference directly within the weighing workflow, while its fanless design avoids introducing additional air movement around highly sensitive samples. The weighing chamber also uses anti-static glass to help shield measurements from external electrostatic interference.

The BM-252 provides a 250 g capacity with 0.01 mg readability, making it well suited for pharmaceutical formulation, chemical analysis, reference-standard preparation, filter weighing, environmental testing, research, quality control, and other applications where extremely small changes in mass must be detected. A&D’s specifications include 0.03 mg repeatability at 100 g and a typical minimum weight of approximately 20 mg, supporting demanding precision-weighing procedures.

Designed for highly sensitive measurements, the BM-252 features a protected weighing chamber that helps minimize the influence of drafts and environmental disturbances. Automatic Response Adjustment can adapt the balance’s response characteristics to environmental vibration and air movement, helping operators optimize stability for actual installation conditions. The BM Series also incorporates environmental monitoring capabilities for temperature, humidity, and atmospheric pressure, providing useful information about conditions that may influence semi-micro weighing performance.

The BM-252 includes internal calibration with automatic self-calibration, allowing the balance to adjust using its internal mass in response to changes in ambient temperature. Users can also initiate one-touch calibration with the internal mass or perform calibration with an external weight when required by laboratory procedures. These capabilities help maintain consistent weighing performance while simplifying routine calibration in regulated laboratories, pharmaceutical operations, research facilities, and quality-control environments.

For professional data management, the BM-252 can store up to 200 weighing results, or up to 100 results with date and time information, as well as calibration and calibration-test records. The balance supports GLP/GMP-oriented reporting and includes a built-in clock and calendar for traceable measurement documentation. These capabilities help organizations integrate high-precision weighing into controlled laboratory and quality-management workflows.

Standard RS-232C and USB connectivity supports integration with compatible computers, printers, laboratory software, and data-collection systems. The BM-252 is also designed to work with data-acquisition accessories for recording weighing results and environmental parameters, helping laboratories streamline measurement documentation and electronic data management.

Whether you’re performing pharmaceutical research, chemical analysis, reference-standard preparation, environmental testing, laboratory sample preparation, formulation, quality control, cannabis testing, filter weighing, static-sensitive material measurement, or scientific research, the A&D Scale PN BM-252 delivers the exceptional resolution and advanced functionality required for demanding semi-micro weighing applications. Its 250 g capacity, 0.00001 g readability, built-in fanless ionizer, automatic internal calibration, anti-static weighing chamber, environmental monitoring, professional data memory, and RS-232C and USB connectivity make it a powerful solution for professional precision-weighing environments.
