A&D Weighing EJ-54D2 EJ Series Portable Balance with External Calibration, 22/52 g x 0.0002/0.001 g

The A&D EJ-54D2 is a dual-range precision balance that automatically switches between two weighing ranges. It offers an ultra-fine readability of 0.0002 g for measurements up to 22 g, then transitions to 0.001 g readability up to 52 g. This design allows users to perform highly detailed measurements while maintaining the flexibility to weigh larger samples on the same instrument.

Yes. The EJ-54D2 is designed for applications requiring exceptional sensitivity, including jewelry weighing, gemstone analysis, pharmaceutical sample preparation, chemical laboratories, and research. It features a draft shield (breeze break), a dedicated carat pan, and high-resolution weighing that minimizes the effects of air movement during delicate measurements.

Beyond standard weighing, the EJ-54D2 includes piece counting, percentage weighing, display hold, and accumulation (M+) functions. The built-in ACAI (Automatic Counting Accuracy Improvement) feature continuously improves counting precision, making the balance useful for inventory counting, formulation, and quality control applications.

Yes. The balance supports both AC power and four AA batteries, making it easy to use in laboratories, classrooms, field research, and mobile testing locations. Its compact footprint, lightweight design, and long battery life make it an excellent choice for users who need accurate weighing in multiple locations.

Yes. The balance can be upgraded with optional USB, RS-232C, or Bluetooth® communication interfaces, allowing users to transfer weighing data to computers, printers, or laboratory software. These connectivity options make it easier to maintain electronic records, improve workflow efficiency, and support GLP/GMP documentation requirements.
