AND Weighing Indicator AD-4401A

AD-4401A
Basic Weighing Indicator

The AD-4401A has a compact body, high-end A/D converter and versatile functions, including batch-weighing control and check weighing.
The AD-4401A is suitable for a wide range of applications, from hopper and packer scales to check-weighing scales.

As a new feature the AD-4401A now is equipped with a High Performance Digital Filter (HPDF). In situations where vibration must be removed, it provides high accuracy as well as high-speed response.

The AD-4401A is highly compatibility with the old AD-4401 model allowing for easy replacement of any old AD-4401 devices. Easily replaceable
