The 216 has a removable scale with a measuring range of 0 to 230 centimetres which can be inserted variably into a 150 centimetre long plastic profile. The measuring rod is simply mounted on the wall at the desired height. This means that the user himself selects the measuring range shown in the profile – the 216 is thus suitable for both adults and children. Already during the measuring process, the exact result is clearly visible in the display window which is positioned at the side of the measuring rod. As the head piece has a lock knob, the result remains visible after the measuring process. A further advantage: the 216 is ideal for international use as the scale is printed on both sides. It can be inserted either way round into the plastic profile so that the result is shown in either centimetres or in centimetres/inches.
