EJ-3002 Portable Precision Balance
Affordable, Accurate, and Portable Weighing for Laboratory, Education, and Field Use
The EJ-3002 delivers precision, versatility, and value in a compact, rugged form factor. With a generous 3100 g capacity and 0.01 g readability, it’s designed to handle a wide range of applications—from educational and laboratory tasks to light industrial and on-the-go weighing. The SG Weighing Technology ensures stability and consistency, while its portability and long battery life make it perfect for shared or mobile workspaces.
This balance supports advanced functionality like percentage weighing, parts counting with ACAI (Automatic Counting Accuracy Improvement), and display hold. External calibration keeps it accurate and compliant, and optional connectivity options—including RS-232C, USB, and LAN via WinCT-Plus—make integration with data systems simple and efficient.
