A&D Scale PN EJ-303 is a professional portable precision balance engineered to deliver laboratory-grade weighing accuracy, reliability, and portability for pharmaceutical laboratories, research facilities, educational institutions, jewelry applications, manufacturing operations, cannabis testing laboratories, and industrial quality control environments. As part of A&D’s trusted Newton EJ Series, the EJ-303 features a 310 g capacity with 0.001 g (1 mg) readability, making it ideal for weighing chemicals, powders, laboratory samples, formulations, precious metals, gemstones, and other materials requiring high-resolution measurements. Built with A&D’s proven Sensor Guide (SG) weighing technology, the EJ-303 combines exceptional precision with a lightweight, affordable design. Its durable ABS housing, 110 mm (4.3 in.) stainless steel weighing pan, and included draft shield (breeze break) provide outstanding measurement stability and portability. The balance utilizes external calibration with a 300 g calibration weight to maintain long-term weighing accuracy.

Designed for demanding laboratory environments, the A&D EJ-303 stabilizes in approximately 5 seconds, allowing operators to complete weighing tasks efficiently while maintaining excellent repeatability. The large 16 mm backlit LCD display provides exceptional visibility in virtually any lighting condition, while the intuitive five-button keypad simplifies zeroing, taring, printing, unit selection, and configuration. Standard weighing modes include normal weighing, piece counting with Automatic Counting Accuracy Improvement (ACAI), percentage weighing, accumulation (M+), display hold, gravity acceleration correction, and comparator functions that improve formulation, packaging, inventory management, shipping, receiving, and quality control operations. The balance operates using either the included AC adapter or four AA batteries, making it ideal for both bench-top and portable field applications.

The EJ-303 supports optional RS-232C, USB, and Ethernet communication interfaces for seamless integration with computers, printers, barcode systems, and laboratory software. Additional features include GLP/GMP/ISO-compliant data output, selectable weighing units, overload protection, security slot, optional wireless communication, density determination kit, under-hook weighing capability, carrying case accessories, and stackable storage. The corrosion-resistant stainless steel weighing pan is easy to clean, while the rugged ABS housing is designed to provide years of dependable operation with minimal maintenance. Its included draft shield helps minimize air currents for improved weighing stability when measuring lightweight samples.

Whether you’re performing laboratory analysis, formulation, production quality assurance, jewelry weighing, scientific research, or industrial precision measurements, the A&D Scale PN EJ-303 delivers the accuracy, durability, and versatility professionals expect from A&D. Its 0.001 g readability, integrated draft shield, portable battery-powered operation, advanced weighing functions, and dependable performance make it an outstanding investment for organizations seeking reliable precision weighing with long-term efficiency and accuracy.
