AND AD-4326 Digital Industrial Scale Indicators

The AD-4326A and AD-4326B digital scale indicators are easy to operate industrial scale indicators for general use and offer outstanding and affordable performance. The AND AD-4326 series of scale indicators come in two versions: with or without a key pad for digital input, and both indicators can be battery or AC operated.

The AD-4326A and AD-4326B set new standards in weighing indicators for outstanding performance, ease of use, and advanced design. These new indicators offer 1/10,000 counts of resolution, an attractive design that may be placed on a desk or wall or column mounted, basic or keyboard design, and a multitude of features.
