Yet the General Electric XRD-3 logarithmic scale permits you to read from 2 to 10,000 counts per second on a single. 10-inch scale Having a dynamic response range of zero to ten thousand counts per second—the XRD- 3 X-RAY accurately records a wide range of intensities. Ratios of sev eral thousand to one are easily visible on a single chart, contrasted to one hundred to one on a linear scale. N o need to search for strongest line before beginning run. N o off scale peaks to cause repeat runs. N o confu sion of multiple linear scale ranges. The X R D - 3 is designed to satisfy your diffraction needs for both film and direct re cording technics.
