15JA Measurement microscopeDetailed product description：

Product Usage
Measurement microscope is a type of optical metrology instrument with a simple structure, easy operation, and a wide range of applications.
1. Measure the length in the Cartesian coordinates of the microscope, such as measuring the hole distance, base distance, groove distance, groove width, keyway width, slit width, outer diameter of the through-hole, etc.
2. Measure the angle of the microscope rotation dial, such as measuring the angle of dials, templates, gauges, drilling templates, and geometrically complex parts.
3. Used as an observation microscope to compare the smoothness of working surfaces and identify ore specimens in the metallurgical industry. Verify printing photographic plate making, inspect textile fibers, and so on.
