Miniature On-line Atmospheric Heavy Metal Monitor

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

GaOA tiny atmospheric heavy metal on-line analyzer is LANScientific co., LTD., fusion X fluorescence nondestructive testing technology, automatic air particulates enrichment technology, independent research and development of the monitoring instrument miniaturization, the advantages of small size, low detection limit, several accurate, high temporal resolution, which can realize the air particles in the heavy metals such as lead, cadmium, chromium, arsenic continuous monitoring, Suitable for grid and dense distribution, it is widely used in urban atmospheric environment monitoring, factory area unorganized emissions, traffic exhaust emission pollution gas monitoring, emergency monitoring and other fields.



Compact and portable instrument, solid structure, easy maintenance, accurate and reliable monitoring data, construction cost is much lower than the standard station, suitable for large area layout fine or grid monitoring.

Low detection limit

Accurate measurement of arsenic, cadmium, chromium, antimony, mercury and other dozens of heavy metals, low detection limit of elements up to 0.01ng/m3, and other elements can be customized according to user requirements.

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.

Cloud platform

The equipment adopts wireless communication technology, the instrument can achieve confidential and secure communication with the server, and gather the big data of the environment into the "cloud platform".

Data transmission

The monitoring data complies with the Data transmission standard of online Automatic Monitoring (Monitoring) System of pollution sources (HJ/T 212-2005). At the same time, users can easily customize the corresponding functions according to the actual needs.


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

Application scenario


Online heavy metal detection after solid waste or garbage incineration
