Description:  This reliable roller distance measuring device is designed for use in straight lines and curves. The measuring wheel is accurate to the nearest centimetre up to 9,999.9 metres. Measured values are shown on the easy-to-read display. A movable indicator provides information on the exact start and final position. Rolling the wheel forwards adds to the measured values while rolling it backwards subtracts. The device has a hold function for locking the current value on the display. Five entries can be stored in the measured value log for documentation purposes. Easy to transport due to folding design.
