Digital scales and balances are precision instruments. People using these instruments should be able to answer these questions:
1. How secure is your weighing data?
2. How accurate are your scales?
3. What is the degree of protection from dust and moisture?
Digital scales and analytical balances play a crucial role across a broad spectrum of industries to help maintain high GLP and GMP standards in pharmaceutical labs and manufacturing, or in any industry where the need for weighing accuracy is paramount. Written operating procedures governing accurate weighing and record keeping go a long way in supporting any organization’s goal to achieve excellence.
What I’ve found is there are discrepancies in how certain digital scale manufacturers describe the performance of their products. Incorrect scale specifications and term definitions can lead to problems when these scales are part of precision manufacturing processes.
A case in point: one website I checked equates readout to accuracy. Readout is what you see on the digital display. A long row of digits may look impressive but if the scale is not calibrated properly it most likely is not accurate. “Accuracy” as defined by weighing-systems.com is the extent to which the weight readout of a scale (the numbers you see) approaches the true value of the quantities being weighed – or counted, or whatever the case may be.
