Description:  This 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 with additional fine scale. Direct measurements can be taken from wall to wall due to the device’s compact design. 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. Convenient use due to accessible brake and zero setting directly on handle. Easy to transport due to folding design.
