HiVol 3000 MegaVol

High Volume Particulate Air Sampler

The HiVol 3000 MegaVol particulate sampler performs remote sampling of particulates and is ideal for heavy metal and radiation exposure monitoring. The particulate sampler is capable of a very high flow rate (150m3/hr), which allows representative particulate samples to be collected in shorter time periods (more samples collected per week) or a larger quantity in the same time period (especially for trace levels) than a standard high volume sampler.

Precise performance

The HiVol 3000 MegaVol is 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).
