Inventory scale is designed for professional counting and weighing. Both memory cells and the possibility of being powered by an accumulator turn this inventory scale in an irreplaceable device. This inventory scale is the ideal instrument to determine the amount of pieces accurately, for instance while carrying out inventories. When piece counting function is active, the single weight of a piece is determined by the scale, but if value is known, it can be entered via the keyboard. If a number of pieces is placed on the scale, the inventory scale will be able to show the weight, the reference weight as well as the amount of pieces placed on it. By means of the optional printer of labels, weighing results can be printed directly. Printing is automatic when the value on the display is stabilized. A previous tare can be performed or it is even possible to introduce the reference weight via the keyboard. RS-232 interface is available for the inventory scale. Through the optional software weighing data can be transferred to a computer.
