Micro balance AND EJ-303

EJ-303 Precision Balance 

Portable Milligram Balance with Draftshield for Precision Weighing on the Go

The EJ-303 is a compact milligram precision balance designed for high-resolution weighing tasks in laboratories, classrooms, field operations, and light industrial settings. With a 310 g capacity and 0.001 g readability, this model offers exceptional accuracy in a portable, user-friendly package—ideal for shared or mobile use.

Powered by SG Weighing Technology, the EJ-303 ensures stable and repeatable performance, while the included draftshield protects sensitive measurements from airflow interference. Users benefit from enhanced productivity features like Display Hold, Accumulation (M+), and ACAI (Automatic Counting Accuracy Improvement) for counting applications. With optional USB, RS-232C, or Ethernet (LAN) connectivity via WinCT-Plus, this balance integrates easily into your data workflow.
