Product Description
AOA 200 Atmospheric heavy metal online analyzer is an online heavy metal continuous monitor fusion of X-ray fluorescence nondestructive testing technology, β -ray absorption detection technology and air particulate matter automatic enrichment technology, in line with the United States 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 at the same time. It can realize the monitoring of low content of lead, cadmium, chromium, arsenic and other heavy metals in the air particles and the collaborative measurement of PM concentration, unattended, and long-term automatic.
