RoHS Tester

RoHS detector is the EU RoHS test standard testing equipment. Simple to say is the test lead Pb, cadmium Cd, mercury Hg, hexavalent chromium Cr6 +, PBDE PBDE, PBB PBB six kinds of harmful substances instruments.


RoHS Directive is the country just enacted "electronic and electrical equipment restrictions on the use of certain hazardous substances," the short name. As its name implies, RoHS detector is a detection ROHS detector, the principle is the use of X-ray detection of ROHS standard elements in the content.


RoHS detector currently on the market, the common type of X-ray fluorescence analyzer, is divided into energy dispersive and wavelength dispersion type, energy dispersive type because of its technical principles and structure than wavelength dispersion type is simple, are more common in the market, the technology principle:

Characteristic X-rays

The X-ray or Γ-ray emitted by the radioisotope source or X-ray generator interacts with the atoms of the elements in the sample and exits the inner electron of the atom. When the outer electron complements the inner electron, it radiates X-ray-characteristic X-rays that are inherent in the atom.


Relationship between element content and characteristic X-ray intensity

Different elements of different characteristics of X-ray energy, according to qualitative analysis; then according to the size of the characteristic X-ray intensity, quantitative analysis.


RoHS detector is to control the manufacturer's products harmful to human health, heavy metal content. Such as air conditioners, washing machines, vacuum cleaners, water heaters, cell phones, these products are often encountered in people's lives, so if excessive levels of heavy metals will affect human health. It is recommended that manufacturers strictly control the heavy metal content to protect the health of consumers.


In addition to the spectrometer, certain sample preparation techniques must be used in order to obtain qualitative and quantitative information on the sample. Spectral analysis and data processing of the obtained intensities must also be carried out.
