1. Purpose:

The digital display measuring microscope is one of the optical measuring instruments. The measuring table can move along the X and Y directions and rotate around the vertical axis. The moving distance in the X and Y directions can be read from the digital reading device. Dial and vernier reading, the instrument is simple in structure, easy to operate, and has a wide range of applications. The main uses are as follows:

1. Measure the length in Cartesian coordinates, such as the hole spacing, base surface distance, scribe width, keyway width, slit width, inner and outer diameters, etc.

2. Rotate the dial to measure the angle, such as the angle measurement of dials, templates, gauges, drilling templates and parts with complex geometric shapes.

3. It can be used as an observation microscope to check the surface finish of the work surface by comparison method, identify ore specimens in the metallurgical industry, verify printing photoengraving, inspect textile fibers, etc.
