D360 is a laboratory measurement instrument includes a wire diameter bench-top laser gauge and a 360° rotary gear, which is probably the single axis measurement instrument delivers highest accuracy and repeatability to measure diameter and ovality of wire sample. D360 allows laboratory, wire factory to measure wire sample in highest accuracy in the industry. The standalone D360 bench-top laser diameter gauge offers probably highest accuracy measurements for very fine wires. A regular dual-axis or triple-axis laser gauge calculate wire ovality with data in two or three directions, but the D360 kit allows hundreds of measurements in 360° to provide the highest accuracy in industry.
