Description

A&D Scale PN HR-250A

A&D Scale PN HR-250A is a professional analytical balance with external calibration designed to deliver precise, reliable weighing performance for laboratories, pharmaceutical facilities, research institutions, chemical analysis, quality control departments, cannabis testing operations, manufacturing, and other applications requiring measurement at the 0.1 mg level. The HR-250A features a 252 g capacity with 0.0001 g (0.1 mg) readability, providing an excellent combination of analytical precision and higher weighing capacity. Its compact footprint makes it especially useful in laboratories where bench space is limited while still providing the accuracy required for demanding analytical workflows.

The A&D HR-250A incorporates A&D’s advanced Compact Super Hybrid Sensor (C-SHS) weighing technology, combining fast response with stable and repeatable measurement performance. The balance provides a stabilization time of approximately 2 seconds, helping improve productivity when multiple samples must be weighed throughout the day. Its 252 g capacity and 0.1 mg readability make it suitable for pharmaceutical ingredients, chemicals, laboratory samples, powders, formulations, precious materials, research samples, and other applications requiring highly accurate measurements.

Designed for precision-focused environments, the HR-250A features a Ø90 mm stainless steel weighing pan enclosed within a removable breeze break that helps protect sensitive measurements from air currents and environmental disturbances. The compact B5-size footprint allows the balance to fit efficiently into crowded laboratory workspaces, while the reverse-backlit LCD display provides clear visibility of weighing results. The balance’s durable construction and practical design support routine use in professional laboratory and quality-control environments.

The HR-250A supports a variety of advanced weighing functions, including standard weighing, piece counting, percentage weighing, statistical calculations, density determination, and under-hook weighing. A shock-absorbing mechanism helps protect the weighing sensor from vertical and transverse overloading, while adjustable response characteristics allow users to optimize balance performance for different environmental conditions. These capabilities make the HR-250A suitable for both routine analytical weighing and more specialized measurement applications.

Standard RS-232C connectivity allows the HR-250A to communicate with compatible computers, printers, and laboratory data systems for weighing data collection and documentation. Optional connectivity solutions can further expand integration capabilities for laboratory and production environments. The balance also supports data-output functions designed for GLP, GMP, GCP, and ISO-oriented workflows, helping organizations maintain documented weighing and quality-control procedures.

Unlike the HR-AZ models with built-in internal calibration, the HR-250A uses external calibration, making it a practical choice for organizations that already maintain certified external calibration weights or established calibration procedures. This configuration combines the performance of A&D’s HR-A analytical platform with a streamlined design for laboratories that do not require an internal calibration mechanism.

Whether you’re performing pharmaceutical research, chemical analysis, laboratory sample preparation, formulation, quality control, cannabis testing, precious material weighing, or scientific measurement, the A&D Scale PN HR-250A delivers the precision, speed, and compact design required for demanding analytical applications. Its 252 g capacity, 0.0001 g readability, approximately 2-second stabilization, C-SHS weighing technology, compact footprint, enclosed weighing chamber, advanced weighing functions, and RS-232C connectivity make it an excellent solution for professional analytical weighing environments.
