A&D Weighing AD-4401A Digital Weighing Indicator
A&D AD-4401A digital weight indicator is ideal for use in industrial environments. Featuring a high performance digital filter to cancel out vibrations, providing superior accuracy in any environment. High speed sampling of 100 times per second, and high display resolution to 16,000 counts.
Large main display and sub display on the front panel are equipped with bright VFD displays to allow for quick confirmation of measurement status and data settings. Operation and setting key switch designed for easy operation.
Monitor & control weighing and batching with external or internal resolution. Fuzzy and Automatic Free Fall Compensation (AFFC) for consistently accurate batching results. Enter control set points through front keys or remotely though external thumb wheels. Sub display provides feedback on all set points & simplifies calibration. Supplementary flow function assures accurate performance on each batch. Compact DIN size housing speeds installation & reduces space. Splash proof front panel and keys (IP-65).
