Horizontal Projection Optical Optimeter (JD2A)

JD2A horizontal projection optimeter

PURPOSE
It measure the shape of the parts through compare the parts and standard measuring block. On the other hand, it can measure internal size through it's internal instruments. It widely used in manufactory, quality testing department and workshop which produce measure and sophisticated parts.

JD2A horizontal projection optimeter
1. Reading from the projection reading screen
2. Adopt new wax screen technology and reading magnifier, it has a symmetry view field's illumination and clear image.
3. It has a high accuracy and reliable data.
4. The optimeter tube on the apparatus can be installed on the machine tool alone. It uses the measuring block to control the precision process.
