The Cely PS-50 comes standard with an internal rechargeable battery, which is charged using a mains adaptor. There is a choice of either a 6kg or 15kg maximum weight capacity. The housing of the scales is made from plastic, and the weighing pan is constructed from stainless steel. The blue LCE backlight display is very easy to read. These scales are ideally suited for use in butchers, bakeries, fish markets, and industrial kitchens.
