Digital Bathroom Scale | ADE BE 2107 Kiana The Kiana bathroom scales are packed with environmentally friendly details. We have dispensed with batteries altogether. And yet the scale works digitally. Thanks to the power display with dynamo principle. Pressing the display three times activates the dynamo and the scale is ready for weighing. The body of the scale is made of the renewable raw material bamboo. The amount of plastic is reduced to a minimum – only the weighing cells and display are made of white, unpainted plastic. The 12 mm thick footprint measures a comfortable 310 x 300, the LCD display 59 x 32 millimetres.
