I. Brief Description
The switch rail reduction value measuring instrument is a specialized railway measuring device used to measure the reduction value of the switch rail relative to the stock rail and the reduction value of the point rail relative to the wing rail. 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. The touch display module is designed for digital readouts, making the operation interface more convenient and minimalist.
