We sell a large variety of kitchen scales from modern digital models to traditional balance scales that use weights. Kitchen scales have long been used to accurately weigh ingredients for use in cooking, a recipe is no good unless the cook has some way of accurately measuring what's needed.
The simplest form of food scales we sell are the spring pocket balances, which are essentially just a high tension spring with a hook on the end, the heavier the object the further the spring will stretch. Most modern scales in fact work using a variation of this method, their displays differ though as some make use of a digital screen display while others make use of a dial. Enjoying a resurgence at the moment are the old fashioned balance food scales that make use of either metric or imperial weights.
