- Model MegaVol 3000 - Dust Sampler

From

The MegaVol 3000 particulate sampler performs remote unattended sampling of particulates and is ideal for heavy metal and radiation exposure monitoring.

The MegaVol is capable of a very high flow rate (150m3/hr) the increased flow rate allows representative particulate samples to be collected in shorter time periods (more samples collected per week) or to collect a larger quantity in the same time period (especially for trace levels) than a standard high volume 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).

Reliable sampling

  • Volumetric flow control automatically corrected to standard reference temperature.
  • Industrial brushless motor (100 000 hours continuous field operation).
  • Weather-proof marine quality anodised aluminium cabinet.
  • Automatic supply voltage monitoring and shutdown facility prevents damage to instrument.

Directional sampling

  • Wind direction and speed used to activate/deactivate sampler.
  • External trigger (0-5VDC) can be used for activating sampling program.

Enhanced communication

  • RS232 output for data collection and remote communication.
  • Filter block and instrument error alarms.
  • Total control of instrument remotely from PC.
  • Simple programming of sampling periods, including daily and weekly programs, with in built ‘1-in-X day’ sampling capability

The MegaVol 3000 dust sampler has the following new features:

  • Higher flow rate (120-150m3/hr) allows sampling of low concentration pollutants such as heavy metals (lead) or radioactive particulates/dust
  • Optional Iodine trap for sampling radioactive particulates/dust

  • Conditional dust sampling based on wind direction, speed and/or time based sampling such as fenceline monitoring
  • Advanced communications (error alerts, filter full alerts and remote instrument control)
  • Total control of instrument remotely from PC
  • Advanced active volumetric flow control system corrects for STP

  • Volumetric flow range:  Nominal 120-150m3/hr
  • Flow accuracy:  Better than ± 1m3/hr
  • Vacuum Capability:  130 mBar max at 150m3/h
  • Temperature range:  0-50oC
  • Filter size:  250 x 200mm (rectangular element)
  • Weight:  45 kg
  • Dimensions:  456 x 456 x 1480 mm (WxDxH) including TSP inlet
  • Power:  200-240V ±10% 50/60 Hz (std)
  • External inputs
    • Wind direction sensor input (10k potentiometer)
    • Wind speed sensor input (contact closure) or alternatively
    • Tipping bucket rain gauge
  • Data storage up to 150 reading (75 hours of 30min averages)
  • Data accessible via GSM modem

The MegaVol 3000 Particulate Sampler provides a flexible platform for remote unattended sampling of heavy metal and radiation exposure in the environment.

The MegaVol has an very high flow rate (120-150m3/hr) which allows it to sample a larger sample of air than a standard unit, and accumulate pollutants that make up a small percentage of pollution (such as heavy metals, radioactive particulates). This accumulated sample provides laboratories with sufficient sample to perform quantitative and qualitative analysis and allows either increased sampling periods (more per week) or greater accuracy in measurements (especially for trace levels).

Optional attachments allow the sampler to measure wind speed and direction which can then be used as triggers to start sampling and fence-line monitoring.

  • Optional Iodine trap for Radiation monitoring
  • Sampling of Total Suspended Particulates (TSP)
  • Advanced active volumetric flow control system automatically corrected to STP conditions.
  • Ability to perform conditional sampling based on wind speed and direction measurements or time based sampling (fence line monitoring).
  • RS232 output for data collection and networking.
  • Internal data logging of WS/WD, temperature, pressure and flow.
  • Simple programming of sampling periods, including daily and weekly programs, with in built ‘1-in-X day’ sampling capability.
  • Automatic supply voltage monitoring and shut-down facility prevents damage to instrument.
  • Weather-proof marine quality anodised aluminium cabinet.
  • Sampler setup via four-line LCD display and keypad.
