I. Purpose
PDP-300B Precise Measuring Projector is an instrument which adopts photo alignment for profile, grating digital display technology move of working stage as precision focusing. It can not only measure profile but also coordinate. Model PDP-300B has the performance of transmission and reflection illumination and the connector for computer. It can be widely used in industry, such as machinery, electronics, clock and watch, and earthquake research, national defense, scientific research etc.
