RCA Abrasion Wear Testers _15JEdigital-display measuring microscope

Use:
Digital-display measuring microscope is one of optical measure instruments. Its measuring worktable may move along with X/Y-direction and rotate with vertical axis. The moving distance of X/Y-direction may be read form digital-display reading installation, and rotary angle may be read from dial and norius. With simple structure and convenient operation, this instrument is widely used and the main use is as following:

Ⅰ Use:
Digital-display measuring microscope is one of optical measure instruments. Its measuring worktable may move along with X/Y-direction and rotate with vertical axis. The moving distance of X/Y-direction may be read form digital-display reading installation, and rotary angle may be read from dial and norius. With simple structure and convenient operation, this instrument is widely used and the main use is as following:
1. Rectangular coordinate measures length, example: hole distance, base level distance, reticle width, key slit width, slit width, inner and outer circle diameter, etc.
2. Rotary dial measures angel, example: dial, sampler, gauge, drilling templet, and other parts with complicated geometrical shape.
3. Used as observing microscope to examine surface cleanness, appraisal ore sample in metallurgy industry, appraisal printing photoengraving, examine weave fiber etc. in comparative method.
