Checking stands offer a safe basis for precise and fast bore gauging, e.g. for the serial production of small components. The MST58 has a measuring stroke of ca. 35 mm, the MST102 of ca. 130 mm. Both are suitable for Split Ball probes, search for reversal point can be omitted. The MST102 as well as the mini fixture KM are suitable for plug gauges BMD. The use of floating holders is of advantage.
