The WH80 and WH80D are professional measuring rods designed for easy and reliable measurement of infants. The measuring rod features a fixed headrest and a sliding footrest for easy positioning of the infant and accurate length measurement. It can be mounted on a table, wall or compatible Wunder scale.

The measuring rod is available in two versions – WH80 with traditional reading and WH80D with electronic reading. The electronic WH80D features a large, easy-to-read LCD display for quick and clear presentation of the measurement result.

Both versions feature a telescopic anodised aluminium construction with ABS measuring paddles. The measuring range is 35–80 cm with a graduation of 1 mm, and measurements can be read in both centimetres and inches. The WH80D is powered by two AAA batteries.
