I. Brief Description
The Switch Rail Reduction Gauge is a specialized railway measuring instrument used to measure the reduction value of switch rails relative to stock rails and the reduction value of point rails relative to wing rails. It employs high-precision displacement sensors for contact measurement. The measuring rod can move laterally along the guide rail to meet measurement needs at different positions. Designed with a touch display module and digital readout, the operation interface is more convenient and simplified.
