The JD-3 projection vertical optical meter is a precision optical mechanical end measurement instrument that measures the external dimensions of parts by comparing standard gauge blocks with the measured components. The instrument adopts the new technology of wax screen and is equipped with a reading magnifying glass. The field of view brightness is uniform, the image quality is clear, the measurement accuracy is high, and the data is stable and reliable. It is particularly convenient for detecting small-sized precision parts. Used in metrology and testing institutes, enterprise metrology rooms, measuring tools and precision parts manufacturing enterprises, it is also one of the teaching instruments in various universities.

1Using standard equipment(Like measuring blocks)Measure the external dimensions of the component using a comparative method with the test piece.

2Verify measuring blocks, gauges, and lines,The thickness of the plate-shaped object and the pitch diameter of the external thread.

3The diameter of cylindrical and spherical workpieces, as well as the external dimensions of precision measuring tools and parts such as parallel planes.

4Measurement of thickness of thin films such as aluminum foil, packaging film, paper, etc.

5One machine dual-use, installing the projection optical mirror tube on the machine tool can directly control the machining size.

6In process control and online measurement, it is used to measure the small displacement of the measured object.
