Frequently Asked Questions

What makes the A&D EJ-303 a good choice for precision laboratory weighing?

The A&D EJ-303 combines a 310 g capacity with 0.001 g (1 mg) readability, making it ideal for laboratories, educational institutions, pharmaceutical work, jewelry applications, and quality control. Its compact footprint, high resolution, and stable performance provide accurate measurements without requiring a large laboratory balance.

Does the A&D EJ-303 include features for counting and formulation tasks?

Yes. The EJ-303 offers piece counting with Automatic Counting Accuracy Improvement (ACAI), percentage weighing, display hold, and accumulation (M+) functions. These features help improve efficiency when counting small components, preparing formulations, performing inventory checks, or completing repetitive weighing tasks.

Can the A&D EJ-303 be used as a portable balance?

Yes. The EJ-303 is designed for both bench-top and portable use. It operates with the included AC adapter or four AA batteries, providing up to approximately 80 hours of battery life (with the backlight off). This makes it a practical solution for classrooms, field testing, and laboratories that require flexible weighing locations.

What connectivity options are available for the A&D EJ-303?

The EJ-303 can be upgraded with optional Quick USB (EJ-02) or RS-232C (EJ-03) communication interfaces, allowing users to transfer weighing data to computers, printers, or laboratory software. An optional density determination kit is also available for applications requiring density measurements.

How does the A&D EJ-303 maintain accurate and repeatable measurements?

The EJ-303 is equipped with an anti-static breeze break, external calibration capability, adjustable response settings for different environments, and a stainless steel weighing pan that resists chemicals and corrosion. These features help minimize the effects of drafts and static electricity while delivering consistent, repeatable weighing results for demanding laboratory applications.
