Retail Scales or Shop Scales, as they are sometimes referred to, are digital weighing scales used to calculate a price based on weight. Most retail scales have access to a front and rear display for the user and customer, and include built-in PLUs (price look ups), also known as price look-ups, for quickly recalling the price of your most popular products based on the product's weight.
In many countries, it is a government requirement for a retail scale to be approved to a standard often called Trade Approved. In the UK and across the European Community, it is a legal requirement for anyone selling goods by weight to ensure the weighing scales they are using are trade approved. Trade approved scales are often labelled as trade stamped, trade approved, CE stamped, verified, class III approved, shop scales, OIML approved to name just a few.
To ensure your retail weighing scale is correct or fit for purpose, your weighing scale must have a sticker with the letter "M" in black on it, a pale blue sticker with an identification number of the verifier (the person who has tested the accuracy) and a CE mark. Also ensure that all seals on the balance are intact.
