AND Micro Balance AD-4404

Multi-Functional High-Speed Digital Weighing Indicator for Industrial Automation

The AND Micro Balance AD-4404 is a powerful, multi-functional digital weighing indicator developed for demanding industrial environments that require fast response, high accuracy, and intelligent control. With a high-speed sampling rate of 100 times per second and an internal A/D resolution of up to 1,000,000 counts, the AD-4404 delivers stable and repeatable measurements even on high-speed production lines.

Designed with advanced checkweighing, batching, and automation features, this indicator integrates comparator functions, programmable triggers, extensive I/O capability, and product memory into a single robust unit. Its bright fluorescent display, bar graph indicator, and visual/audio alerts allow operators to make instant judgments, improving efficiency and reducing errors in production and inspection processes.
