JD3 Projection Vertical Optical Meter Introduction: The projection optical meter is a precision optical mechanical length measuring instrument. It utilizes the method of comparing standard gauge blocks with the measured parts to measure the slight dimensional differences in the shape of components. It is one of the commonly used precision instruments in factory metrology rooms, workshop verification stations, or workshops that manufacture measuring tools, instruments, and precision components. It can verify gauge blocks and high-precision cylindrical gauge blocks, and can compare the diameters of cylindrical and spherical workpieces, the thickness of template workpieces, and the pitch diameter of external threads. Features: 1. Utilizing the new screen technology, and incorporating a reading magnifier, the visual field brightness is uniform, resulting in a clear image quality. 2. The instrument boasts high measurement accuracy and stable, reliable data, facilitating convenient and quick inspection of small-sized precision parts. 3. The instrument boasts a compact structural design and a small external size, facilitating easy transportation. 4. With dual-purpose functionality, the projection optical lens tube can be removed and installed on the machine tool to directly control the machining dimensions. Technical Specifications: 1.
