    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

    • The size, color and methods of operation and control panel installation of the AD-4401A remains the same as the AD-4401.
    • Interface connectors retain compatibility so even when updating from AD-4401 to AD-4401A previously connected devices can continue to be used without changing any connectors.
    • Functions have been added but the default settings remain identical to the AD-4401.
