EHM-6618Atmospheric monitoring

Product introduction：

Atmospheric heavy metal on-line analyzer is a dual function fully automatic on-line analysis instrument, which combines X-ray fluorescence (XRF) non-destructive testing technology, beta ray absorption testing technology and air particulate matter automatic enrichment technology, and conforms to the American EPA io-3.3 standard method. It can not only monitor the mass concentration of air particles, but also quantitatively analyze the elements in the particles.

The instrument has a detection limit of 10pg / m3, which can be widely used in air quality monitoring, pollution tracing and source analysis, environmental assessment and other fields.
