SciAps X-550 XRF Analyzer

Now, an XRF specifically for NDT: the SciAps X-550 XRF analyzer.  The X-550 sets a new performance standard for handheld XRF. It’s the lightest, fastest, most articulate x-ray gun ever made — 2.8 lbs. including battery — and delivers the small size, high speed and high precision of the SciAps X Series in a perfectly balanced device. The X-550 was especially designed for NDT, PMI users who must access hard-to-reach test locations and welds.

The SciAps X-550 features a powerful, miniaturized x-ray tube designed to excel at measuring low atomic number elements Si, P, S, Mg and Al. This tube combined with highly optimal internal geometry yields fast, precise results on previously challenging applications like measuring silicon for sulfidic corrosion, and low magnesium in aluminum alloys.

The X-550 analyzes common alloys in 1 second or less. For alloys requiring longer test times or two-beam analysis, pre-configured on-board apps assure quality testing by every operator. Tap the Residuals App, for example, and the analyzer uses pre-set testing times to measure low concentrations of Cr, Cu and Ni, then calculates the sum. Operators won’t be adjusting test times in the field, or generating insufficient data quality due to incorrect testing times. The patent-pending Aluminum App is optimized for both low atomic number elements and transition metals for ultra-fast, highly specific verification of the many similar aluminum grades. Grades 3003/3004/3005, Cast 356 and 357, and 2014/2024 are just a few examples that are easy for the X-550, but often confound other X-ray guns.


Delivers PMI for most alloys in 1 second with excellent precision.

Some NDT-PMI applications require longer tests, or multiple beam tests. Our Android apps-based platform provides pre-configured, dedicated apps to make quality testing by every operator as easy as using a smartphone – including apps for residuals (API 751), sulfidic corrosion (API 939), API 5L and other testing.

Optimized for key PMI applications like Residuals and Sulfidic Corrosion.

For many PMI applications, fast tests are sufficient for verification of alloy grade and geochemistry. More complicated applications require longer test times or multi-beam operations (one beam optimized for transition and heavy metals; the other for low atomic number elements Mg, Si, Al, P and S). Dedicated apps ensure testing follows correct procedures, such as recommended test times and X-ray beam settings. For example, the Residuals app defaults to 15-second test times due to the need to measure Ni, Cr and Cu at <0.03% each (sum <0.15%) and Nb and V at <0.02%. The Sulfidic Corrosion app is preconfigured to require two-beam tests in order to measure Si down to 0.03% in steels.

Designed for NDT, PMI users to access hard-to-reach test locations and welds.

Perfectly balanced, light weight, and articulate, you can test all day long without fatigue. The narrow footprint permits total access to virtually any test location and weld.


Great on high temp alloys and precious metals.

 Like most XRFs, the -550 provides fast, precise chemistry on the wide array of high temperature alloys, stainless, red metals and precious metals.  What’s different is the toughness of this metal-framed analyzer, that’s yet incredibly light weight (< 2.8 lbs.) and in perfect balance. Use it for sorting all day long without fatigue. The on-board cell phone camera (macro camera) allows for photo-documentation of materials tested, and the Bluetooth label printer provides instant hard copy labels with time/date stamp, grade ID and chemistry.

Featuring the Aluminum App: Sort all your Al alloys in 1-2 seconds.

 If you’re a scrap processor, the one reason to buy the X-550 over the X-505 is the blazing speed and accuracy on aluminum alloys. The X-550 features our patent pending Aluminum App.  It sorts your aluminum alloys in 1-2 seconds, including those alloys that differ only by magnesium (Mg) content.  Grades that were either impossible to sort with other XRFs or take minutes of testing time, such as 3003/3004/3005, cast 356 and 357, and 2014/2024, are just a few examples. You can now sort many similar Al grades economically. See our “Guide to Aluminum Alloy Sorting.”

Contaminant Phosphorus & Sulfur.

The high powered X-ray tube in the X-550 provides fast analysis of phosphorus (P) in copper and P and sulfur (S) in steels and stainless, allowing you to economically upgrade your copper and ferrous material based on low P and S levels.  The X-550 is 3x faster on P and S than is the X-505 or competing XRFs. Faster testing times make upgrading material for low P and S more economical.

Tramp Elements.

Scrap processing has moved beyond just grade sorting. Many consumers now demand analysis on tramp or residual elements in common steel, nickel and copper alloys. The X-505 is optimized for low detection limits on common tramp elements, including Cr, Ni, Cu, V, Nb, Mo in steels, Pb and Bi in nickel alloys, and various undesired elements in copper alloys.

Connectivity and Android

The X Series is built on Google’s Android platform for real time data exporting. The user interface has the feel of a smartphone with results easily viewed on a vibrant display and reversible light/dark for all lighting conditions. Built-in Wi-Fi, Bluetooth, GPS and USB mean that users can print and email from the X and connect to virtually any information management system for efficient test data and reporting.
