The chart is made from tear resistant low expansion coefficient paper with a wax type coated recording face. Printed on the chart are concentric 24hr time scales divided into five-minute intervals. The outer area of the chart records kilometres per hour by means of speed stylus, which compresses the wax upper surface allowing the black coloured backing paper to reveal the trace.
