Stevens PPR II print-punch traffic recorder: a microprocessor-controlled electro-mechanical recorder that converts output pulses from an air switch or magnetic loop detector to a permanent printed and punched record. Data are recorded on a one inch wide paper tape in ASCII (American Standard Code for Information Interchange) punching format and printed in Arabic numerals along the edge beside the corresponding punched information. The recording interval is controlled by an integral timer with switch-selected intervals in 5 minute increments from 5 to 60 minutes.
This counter was purchased (c.1979) by the Department of Highways of Lothian Regional Council and was used to count traffic at a number of locations in Lothian Region. They were replaced by Golden River counters.
