Length gauges for measuring stations and multi-gauging fixtures
Length gauges from HEIDENHAIN and NUMERIK JENA deliver high accuracy, even over large measuring ranges. They are commonly used wherever fast, reliable, and accurate measurements are required, such as in production metrology, multi-gauging fixtures, measuring equipment monitoring, and position measurement.
