* Welcome To X-ray Machine *



The following 3 types are high precision units with relatively low radiant intensity diffracted through double crystals. It is mainly used to measure the orientation of quartz wafer and other single crystal materials with a high precision. All technical specifications of this series conform to China Standard and coincide with similar foreign products.
