X-555 XRF Analyzer

Premium performance begins with the most advanced handheld XRF technology available, led by a 55 kV X-ray tube for extra low detection limits on key elements like Ag, Cd, Sn, Sb, and Ba. Up to three automated beam settings provide optimal performance across the entire periodic table from Mg to U. All in a rugged instrument with state-of-the-art software and outstanding thermal dissipation.

In Use Globally

Best-in-class light element performance for ultra low detection limits of elements like Mg, Al, Si, P, and S, while also packing enough power to achieve impressive precision on heavy elements like pathfinders Ag, Sn, Sb, and rare earth elements.

Appropriate filtering to optimize sensitivity — 2x better analysis of cadmium detection than any other XRF!  Packs the industry’s most powerful X-ray tube for superior limits of detection—especially for cadmium, silver, tin, antimony and barium. When combined with the new Z-901 Beryllium, get 13 EPA Priority Pollutant Metals. Operators can upgrade the Z-901 Lithium to include lithium, boron, carbon, nitrogen, fluorine, and sodium in their tests, too.

Regulatory Markets
Next-generation connectivity, test data management and reporting for the full range of compliance testing applications, including RoHS, Halogen Free, CPSIA, and lead paint in children’s playgrounds. State-of-the-art data management incorporated into a flexible Android system allows for the greatest customization and data management capabilities. Read more: SciAps for Regulatory Compliance.

Electric Vehicle and Strategic Metals
The 55 kV operation, rather than the industry typical 50 kV, delivers higher performance for critical “light” REEs and some “heavy” REEs, making it a superior option for REE analysis globally. Read more: SciAps for Electric Vehicle & Strategic Metals.

SciAps XRF analyzers are the lightest ever made, weighing in at just under 3 lbs. with battery. The durable aerospace-grade aluminum frame passes the Oops Test and the falling-from-a-35-foot-tower test. Redesigned housing with improved heat dissipation allows for high throughput testing that our customers demand. A narrow, slender form factor accesses the toughest test locations, with a 2.7″ display for rear viewing of grade and chemistry. Download the specifications.
