A: 1,000ppm (hexavalent chromium), 100ppm (cadmium), 1,000ppm (mercury), 1,000ppm (lead), 1,000 ppm (polybrominated biphenyls) and 1,000ppm (polybrominated diphenyl ethers).

A: Our products have passed the certification of the National Environmental Radiation Research and Monitoring Center and the radiation is far below the national standard (2,500ngy limited rate). At the same time, the instrument has a triple –ray protective function, so it will cause no harm to human body or direct or indirect environmental contamination.

A: Our equipment is made in China; but important components are imports, for example, detectors and fluorescent tubes are imported from the USA.

A: Principle: Stream of electrons generated through high voltage flows into the X-ray tube and target material shall generate primary X-rays, which shoot into the sample products being tested after filter and aggregation and generate secondary X-rays, that is X fluorescence we usually refer. After being detected by the detector, X fluorescence is amplified and undergoes data reduction, which is entered the computer. Finally, the computer calculates the results we need.

A: There are English ones but no in Traditional Chinese. Our software is mainly in English and Chinese. For ROHS software, it comes with a third-party language editing function; any other languages can be edited into according to customers’ requirements.
