Compared to previous memory printers we recently developed a perfect solution for collecting, recording and archiving data which have to be collected under ‘legal for trade’ liability.
Our M4501 data storage device joins our legal for trade weighing indicator R420-K402 to a non legal for trade user software. Just mount it at the back of the indicator. In this manner weighing results can be saved in a ‘legal for trade’ storage device.

Thus guarantees that data may not be manipulated and the application can always be identified.

Typical applications:
• Truck Scales
• Dosing Systems
• Onboard Weighing
• Filling Processes
