Measures in feet and inches, and runs on steel rollers. Eraser’s WMI Series Measuring Meters are specifically designed to measure long lengths of wire, cable, flat cable and other flexible materials used in the electrical, electronic and associated industries. Units are available measuring in feet and inches and are self-adjusting for material diameter or width. A digital counter records the amount of material measured. In cases where the material to be measured has a hard, uneven, or slippery outside jacket, the WMIU with urethane rollers may provide better accuracy.
