SciAps Handheld XRF Analyzer X-550
The premium standard for portable XRF — ultralight, blazing fast, and the most articulate XRF gun ever made.
At 2.98 lbs., the SciAps X-550 handheld XRF analyzer delivers alloy grade and chemistry in 1–2 seconds. Its class-leading 50 kV, 500 µA tube runs 3× the light-element power of a standard XRF — so even magnesium, aluminum, and silicon resolve fast.
One Analyzer, Endless Possibilities
Every X-550 is the same 2.98 lb. analyzer on the same Android platform.

X-550 Pb
Simply the best lead paint analyzer ever made
The X-550 Pb uses an X-ray tube instead of a radioactive isotope — no isotope replacement or disposal, no radioactive-materials burden. It's the first non-isotope handheld XRF with accepted HUD PCS at three action levels (1.0, 0.7, 0.5 mg/cm²), with no false positives, false negatives, or inconclusive tests. Tests run in 2–6 seconds and never slow down; the X-ray tube carries a 5-year guarantee.
- Rhodium anode — best if you also perform alloy testing or geochemistry.
- Gold anode — best if you also want soil, RoHS, or environmental metals.
- Optional apps: Lead in Soil, Alloy, Geochem, Empirical, Environmental Metals.
- Tube guarantee
- 5 years
- 1Excitation source — 40 kV, 4 W X-ray tube, Rh or Au anode
- 2Test speed — 2–6 s (auto-terminated at 95%)
- 3Analytical range — Pb standard; up to 32 elements with upgrades

Where the X-550 goes to work
Frequently Asked Questions
How fast does the SciAps X-550 sort aluminum?
The X-550 measures magnesium down to 0.25% in about 2 seconds using its patented Aluminum App, so it separates aluminum grades that differ only by chemistry — like 3003/3004 or 356/357 — where slower guns force a downgrade or a 20-second test.
Is the X-550 Pb lead paint analyzer radioactive?
No. The X-550 Pb uses an X-ray tube, not a radioactive isotope, and holds accepted HUD PCS at all three action levels (1.0, 0.7, 0.5 mg/cm²) with no inconclusive range — eliminating isotope replacement, disposal, and licensing.
What is Detector Protector Technology on the X-550?
DPT is a rigid, fine-grid, high-strength window that prevents the detector punctures common when jamming an analyzer into turnings. It's standard on X-550 units with the Alloy App, and across 1,000+ DPT units in the field, not one detector has been punctured.
Should I buy the X-550 or the X-505?
Choose the X-550 for the fastest aluminum sorting, the lowest P/S test times, or lead-paint capability. Choose the X-505 for the same transition/heavy-metal precision at a lower price when a few extra seconds on light elements is acceptable.
Get Both With OneBox
Pair the X-550 with a SciAps Z-Series LIBS and cover every element and sample type — same batteries, cables, chargers, and accessories. LIBS analyzes what XRF can't (Li, Be, B, C, F, Na); XRF is great for transition and heavy metals.
