Features
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
