SciAps Handheld XRF Analyzer X-505
Premium alloy performance at a lower price — the workhorse of the premium X-Series.
At 2.98 lbs., the X-505 runs a 50 kV, 5 W tube and a 25 mm² silicon drift detector, verifying alloy grade and chemistry in 1–2 seconds. It matches the X-550 on transition and heavy metals — the only difference is a few extra seconds on the light elements.
One Analyzer, Endless Possibilities
The X-505 is one analyzer, configured for the work you do. Toggle to the build that matches your samples — every one shares the same 2.98 lb. body, Android software, and accessories.
X-505 Mining
Geochemistry on rock faces and core
The Mining App carries optimised calibrations for 36 elements, from magnesium through uranium, for rapid geochemical analysis across a wide range of geological materials. Micro and macro cameras pinpoint the exact spot tested on a vein, an inclusion, or a rock face — and document it.

The Flagship Build, at a Lower Price
- 01
The Same Hardware as the Flagship
The same rugged, mostly-metal frame and the same 25 mm² silicon drift detector as the X-550 — the difference is tube current, not build quality.
- 02
2.98 lbs., All Day
Ultralight and balanced rather than nose-heavy, so a full shift of testing doesn't cost you an arm.
- 03
Reaches Awkward Welds
A slender snout and narrow footprint get into the test locations that defeat bulkier guns, with a rear-facing display you can still read at the point of test.
- 04
Doesn't Quit in the Heat
Excellent thermal handling for continuous testing in the hottest climates — no drift, no waiting for the gun to cool down.
- 05
Shares Your Fleet's Kit
The same batteries, chargers, cables, cases and consumables as every other X-Series analyzer, so a mixed fleet carries one set of spares.
- 06
Lowest Service Costs
SciAps builds its own tubes and detectors, which keeps repairs component-level and the cost of ownership down over the life of the instrument.

Where the X-505 goes to work
Frequently Asked Questions
What's the difference between the X-505 and the X-550?
They share the same 25 mm² detector and the same speed on transition and heavy metals. The difference is tube current: the X-550 runs 500 µA against the X-505's 200 µA, roughly 3× the power in the low-voltage beam, so the light elements resolve faster. In practice: 0.3% magnesium in an aluminum alloy takes about 2 seconds on the X-550 versus 7 on the X-505 (sorting 356 from 357), and 0.1% silicon in steel for sulfidic corrosion takes about 6 seconds versus 16. Phosphorus, sulfur and the low-Z majors in mining samples follow the same roughly 3× pattern. Everything else is equal — the X-505 reaches the same answer a few seconds later, at a lower price.
Can the X-505 sort aluminum alloys?
Yes. It was engineered for good magnesium and silicon sensitivity and sorts most aluminum grades well — just a few seconds slower than the X-550's Aluminum App. For high-volume aluminum sorting, the X-550 is faster.
Is the X-505 available for catalytic converters and gold?
Yes — the X-505 offers a Car Cat app for platinum, palladium, and rhodium, and the detectORE app for in-field gold and silver, alongside alloy, mining, soil, RoHS, and precious-metals configurations.
Does the X-505 support custom calibrations?
Yes — the Empirical app lets you define beam conditions and elements and build custom calibrations in SciAps Profile Builder, so the X-505 can handle proprietary or unusual materials beyond alloys, ores, and polymers.
Get Both With OneBox
Pair the X-505 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.
