The movable length of the workpiece and the rotation angle on the projection screen can be digitally displayed
With a non-spherical collector lighting system, the visual field of the projector screen would be all the more bright and homogeneous thus reducing measurement errors and further securing the accuracy
With axial flow blower fans, the bilateral heat radiation can provide super-strong radiating power
Imported Phillips long-life halogen tungsten lamps are adopted to satisfy the requirement of long-time uses of the projector
JT12A-C has a built-in feeder box, RS232 interface and 2-coordinate measuring software with strong function
JT12A-Z has a multi-function digital indicator and micro-printer

This instrument is a precession measuring device integrating optics, mechanics, electricity and computation into an organic whole; which is widely used in the measuring rooms and workshops of related factories and plants in the sectors of machinery manufacture, instrumentation, clocks and watches and electronics industries. This instrument can easily and speedily check the profiles and surface shapes of various measured parts; e.g., various parts, cutting tools and tools of sample plates, punching pieces, cams, gears, molding milling cutters, tapping tools, etc.
