Measuring Microscope 15J 15J Standard type 15JA With lighting devices 15JE Digital Use： Measurement of optical microscopy is one of the measurement apparatus, it is simple, easy to operate, a very wide scope of application and the main use is as follows: 1. Determination of the length of rectangular coordinates, such as the determination of Distance, distance-based, groove width, keyway width, slit width, diameter cylindrical hole and so on. 2. Determination of angle of rotation dials, such as dial, model, gauge, drilling template and parts of complex geometry for angle measurement. 3. Microscope for observation to compare the surface finishes inspection method, identification of metallurgical industry ore specimens. Test photo-offset printing, testing and so on textile fibers. 15J 15JE（Digital display resolution：0.001㎜） Specification： 1.
