Commercial Restaurant Food Scales are an absolute 'must-have' in the kitchen. Scales are broken down into the following categories: All Purpose, Bakers, Receiving, Portion Control and Retail aka/'Legal for Trade.' Within these categories are Standard Spring Type Mechanical and Digital Scales. Some of the terms as "Air Dash" imply that they have a mechanical mechanism that eliminates the bouncing of the indicator needle, which in turn is a faster visual read. The term "Slant Face" simply states that the scale has a face that is slanted upward for a more ergonomic view for the operator. The term "Portion Control" indicates that the scale has a dial on the indicator face that enables one to 'tare' or zero out the weight of the tray that food product is resting on. The term "Digital" tells you that it is powered by battery or cord and has a digital read out. Lastly, the "Retail" or "Legal for Trade" is the type of scale that is needed when computing prices for food by their weights.
