The Benchmark 14H bench top comparator, a horizontal comparator, has an erect projection image, and our "ultraprecision" crossed roller bearing stage system. The measurement scales have zero backlash and are mounted in the center of the stage travel that provides maximum measurement accuracy. The system is available with Dorsey's Internal Edge Detection and the extra long-life LED surface illumination, another Dorsey innovation. Like Dorsey's other models, the Benchmark 14H is built to last, is designed for shop floor use and has the same high quality features as the current product line that Dorsey is well known for in the industry.
