drylin® W - Digital measuring system


The drylin® WKM measuring systems are stand alone units independent of mains. The integrated battery guarantees a multi-year operating life. This makes a quasi-absolute distance measurement possible. Magnetic tapes are used as a standard. The position value is displayed by means of a 5-digit LC display.
