The X-550 is now the top-selling XRF (X-ray fluorescence) hand-held metals analyzer for scrap processing. The analyzer sorts very similar grades of aluminum alloys in up to two seconds – as fast as stainless and high-temperature alloys. The system's X-ray technology measures magnesium and silicon as fast as it measures nickel, chromium, cobalt and other high-temperature metals. The result is the X-550. Watch it in action here.
