The Niton XL3 800 Series of handheld XRF analyzers provides alloy-grade identification and laboratory-quality composition analysis of metal alloys. Typical time for routine positive grade identification is less than two seconds. The series is available in a range of configurations, with an assortment of optional features and accessories. The analyzers are suited for scrap recycling, PMI (positive material identification) programs, and metal fabrication and manufacturing applications. The analyzers have 50-kilovolt, 2-watt X-ray tubes and incorporate 80-megahertz, real-time digital signal processing and dual embedded processors for computation, data storage, communication and other functions. The analyzers come with Niton data transfer software, and a suite of data management utilities that allows operators to produce certificates and reports, as well as monitor or operate the instrument remotely from a PC or PDA. The file format preserves and protects the data from each sample analysis, ensuring that data is not intentionally or unintentionally compromised.
