American Ecotech - Model HiVol 3000 -MegaVol High Volume Dust Sampler

The MegaVol is therefore ideally suited for sampling particulates that make up a small percentage of the total sample (heavy metals, radioactive particulates etc.) and provides laboratories with sufficient material to perform quantitative and qualitative analysis.

Optional attachments allow the sampler to measure wind speed and direction which can then be used to trigger sector selectable sampling (e.g. fence-line monitoring).

The sampler software can also double as a remotely accessible data logger for simple weather monitoring (wind speed and direction, temperature, humidity and rainfall).

• Volumetric flow control automatically corrected to standard reference temperature.
• Industrial brushless motor (100 000 hours continuous field operation).
