Atmospheric Heavy Metal On-line Monitor

Contributing to a green future
Atmospheric Heavy Metal On-line Monitor

AOA 200 Atmospheric heavy metal online analyzer is an online heavy metal continuous monitor independently developed by LANScientific 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.

Advantage

Detection range

Accurate measurement of lead, cadmium, chromium, arsenic and other dozens of heavy metals, low detection limit of elements, and other elements can be customized according to user requirements.

Flexibility

The main engine adopts international standard chassis, which can be installed on mobile monitoring vehicle or standard cabinet of automatic air station.

High precision

No miscellaneous peak light path design, built-in multi-file light filter, automatic switching to achieve low background measurement.

Automatic calibration

Built-in calibration module, XRF spectrum horizontal and vertical coordinates at the same time automatic calibration, calibration frequency can be set arbitrarily, but also built-in specific metal internal standard source, can realize automatic quality control and alarm.

Data transmission

With RS232/485, USB, GPRS, ADSL, Ethernet and other data transmission modes, it can realize remote transmission, monitoring and inspection of operation parameters, status and data.

Safety

Professional multiple anti-radiation treatment, no radiation leakage in all directions when measuring instrument.
