A&D EJ-54D2 Dual Range Portable Balance 22/52 gx 0.0002/0.001mg ExtCal

Description

Product Overview

The A&D EJ-54D2 Dual Range Portable Balance is engineered for high‑precision laboratory applications where both macro and micro measurements are required. With a dual‑range capability of 22‑52 g for routine weighing and an ultra‑fine range of 0.0002‑0.001 mg for trace analysis, this balance delivers repeatable accuracy across a broad spectrum of sample sizes. The compact footprint—measuring 12.4 × 10.83 × 7.67 inches and weighing only 4.4 lb—makes it ideal for benchtop deployment in research labs, quality‑control stations, and field‑portable setups. Built with a stainless‑steel chassis and a high‑resolution LCD display, the unit provides clear readouts even in bright environments. External calibration (Ext Cal) allows users to maintain traceability without dismantling the instrument, while the built‑in counting mode with Automatic Counting Accuracy Improvement (ACAI) streamlines inventory checks and particle counting tasks. Multiple unit options—including g, oz, lb, ct, pcs, and %—enable seamless integration into existing workflows, and the percent mode displays weight as a proportion of a reference mass for rapid comparative analysis.

Usage

Designed for versatility, the EJ-54D2 excels in a variety of laboratory and industrial settings. In pharmaceutical formulation labs, the ultra‑fine range supports active ingredient dosing at sub‑milligram levels, ensuring batch consistency. In materials science research, the dual‑range function allows quick switching between bulk sample weighing and nanoparticle mass determination without changing equipment. Quality‑control technicians benefit from the counting mode when verifying tablet counts or component inventories, while the percent mode simplifies comparative studies such as moisture content analysis against a known standard. The balance’s robust construction tolerates typical bench vibrations, and its compact size fits comfortably in safety‑critical environments where space is at a premium. Whether used on a stable laboratory bench, a clean‑room work station, or a portable field kit, the EJ-54D2 provides reliable performance with minimal setup time.

FAQ

What is the maximum load the balance can handle?

The primary range supports up to 52 g, while the micro‑range is limited to 0.001 mg. Exceeding these limits may affect accuracy and should be avoided.

Can the balance be used for counting small parts?

Yes. The built‑in counting mode, enhanced by ACAI, accurately counts items such as tablets, beads, or components when a known reference weight is entered.

How often should external calibration be performed?

Calibration frequency depends on usage intensity and regulatory requirements. For most laboratory environments, a quarterly calibration is recommended to maintain optimal performance.

Is the balance compatible with laboratory software?

The EJ-54D2 includes a USB interface and supports standard data export formats (CSV, TXT), allowing seamless integration with most LIMS and data‑analysis software.

What warranty and service options are available?

A&D provides a 12‑month limited warranty covering parts and labor. Extended service contracts and on‑site calibration services are also available upon request.
