ProScale ProTouch IV

The ProScale ProTouch IV cleverly disguises a high-precision scale beneath an exterior that resembles many popular touchscreen smartphones. The removable protective cover of the ProTouch IV conceals the scale display and stainless steel weighing platform, but also doubles as an expansion tray when weighing larger items. The ProScale ProTouch IV also features a large backlit LCD display, an easy-to-use 3-button interface and 6 different weighing modes.
