JT21 Φ 350 digital measuring projector
1、 Purpose:
JT21 Φ 350 digital measuring projectorCapable of efficiently detecting the contours and surface shapes of various complex shaped workpieces, such as templates, stamped parts, camshafts, gears, forming milling cutters, wire taps, and other cutting tools, tools, and parts. Because the 350mm projection screen tilts forward, it is suitable for comparative measurement checks such as drawing projected images and observing contour shapes.
JT21 Φ 350 digital measuring projectorWidely used in metrology rooms and workshops related to factories and mines in the mechanical manufacturing, instrumentation, and watch industries.
