Handheld XRF (X-ray fluorescence) analyzers are compact, portable devices that utilize X-ray technology to determine the elemental composition of materials rapidly and non-destructively. By emitting primary X-rays onto a sample and analyzing the secondary (fluorescent) X-rays emitted in response, these analyzers can identify elements and determine their concentrations present in a wide range of materials with exceptional speed and accuracy.

Features of Mark 900 XRF Alloy Tester
●Light & small, ergonomic handle design, equipped with a special instrument case, easier to grasp and more convenient to use in the field.
●5-inch high-definition screen with 360-degree rotation, multiple points operating, can display clearly at any lights.
●Integrated design of Seal type, with waterproof and dustproof function, can be used continuously in harsh environments.
●Directly measure and analyze the surface of samples and goods. Can do a quick measurement by its handheld benefit and accurately test samples for a long time by its test block.
●Rapid non-destructive detection and quick measurement by aiming, to report results within one second. Comparable to the bench-top XRF, fast and accurate.
●Simultaneous detection of Ti)V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Sb, Hf, Ta, W, Re, Pt, Au, Pb, Bi, Mg, Al, Si, P, S, and it can add customized elements.
●The instrument can run without helium by the ultra near optical path design and can detect the light elements from the beginning of Mg that fully meets the needs of specific users.
●A large lithium battery at 27000mAh could be a selected configuration; the battery duration working time is up to three days, and it is equipped with a communicator and car charger to ensure power supply.
●A Built-in memory battery can continue to replace the battery power.
●Intelligent-tricolor-early-warning-system: 360 degrees without dead angle display by LED three-color lamp design. Instrument status is shown in different colors: Green light means power on; Red flushing means testing; Yellow flushing means fault.
●Triple safety protection function:
a: Automatic induction, the instrument does not work without sample, no leakage radiation.
b: Thicken – preventing – testing – wall can effectively prevent the scattering.
c: Safety – protection – cover can prevent the surrounding light matrix scattering.
●Security-linkage-locking device protects your security; it can guard the final checkpoint if the software is unable to control the instrument turned off.
