School tachometer - roadside meter with meter

MACHINE TRANSLATION (not authorised yet)

The distance meter, a wheeled distance measuring device, is the perfect measuring tool for children, adapted to their age in terms of dimensions and form, which allows them to measure distances and determine shapes, angles and surfaces. On the moving measuring wheel, to which the handle is attached (83 cm in total), there is a mechanism which, with a click, informs about the full rotation of the wheel (= 1 metre). A counter can be purchased for the odometer.
