Description

A&D Scale PN HR-250AZ

A&D Scale PN HR-250AZ is a professional analytical balance with internal 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-250AZ 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-250AZ incorporates A&D’s advanced Compact Super Hybrid Sensor (C-SHS) weighing technology, combining fast response with stable and repeatable measurement performance. When configured for fast response under suitable environmental conditions, the balance can stabilize in approximately 2 seconds. Repeatability is 0.1 mg from 0 to 200 g and 0.2 mg from 200 to 252 g, with ±0.3 mg linearity. These specifications make the HR-250AZ 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-250AZ features a Ø90 mm stainless steel weighing pan enclosed within a removable, shatter-resistant breeze break with an antistatic coating. The balance has a compact footprint of approximately 198 × 294 mm, smaller than an A4 sheet of paper, helping conserve valuable laboratory bench space. Rotary sliding doors provide convenient access to the weighing chamber without requiring additional clearance behind the balance, while the reverse-backlit LCD provides clear visibility of weighing results.

A key advantage of the HR-250AZ over the HR-250A is its built-in internal calibration mass. The HR-AZ series supports convenient one-touch calibration using the internal mass, helping users maintain dependable weighing accuracy without routinely handling separate external calibration weights. This feature is especially valuable in regulated laboratories, quality-control departments, and other environments where consistent balance performance and efficient calibration procedures are important.

The HR-250AZ supports a variety of advanced weighing functions, including standard weighing, piece counting with Automatic Counting Accuracy Improvement (ACAI), percentage weighing, statistical calculations, comparator functions, density determination, and under-hook weighing. Adjustable response characteristics help users optimize performance in environments affected by drafts or vibration, while GLP, GMP, GCP, and ISO-oriented output capabilities support documented laboratory and quality-control workflows.

Standard RS-232C connectivity supports integration with compatible computers, printers, data-collection systems, and laboratory equipment. Optional accessories and interfaces can further expand the balance for specialized laboratory and production applications. Combined with its compact design, internal calibration, analytical resolution, and advanced weighing functions, the HR-250AZ provides a versatile solution for professional organizations requiring accurate and repeatable measurement.

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-250AZ delivers the precision, speed, and convenience required for demanding analytical applications. Its 252 g capacity, 0.0001 g readability, internal calibration, approximately 2-second fast stabilization, C-SHS weighing technology, compact footprint, Ø90 mm weighing pan, enclosed weighing chamber, advanced weighing functions, and RS-232C connectivity make it an excellent solution for professional analytical weighing environments.
