  Environmental Devices Corporation is an innovative global leader in real-time particulate monitors and is the first manufacturer to offer a turnkey portable wireless video dust monitor that is complete and affordable.

Digitally Record Work Place Exposures:
The VDM-7500 measures the levels of lung damaging particulates while simultaneously overlaying dust concentration on to video images. All data is displayed real-time on the computer screen. This technique allows the investigator to record and obtain certain events that are clearly linked to workers exposure of airborne contaminates. This provides a more effective and focused way to implementing recommendations for controlling employee health.

Actually see, record, and store streaming video and dust data of lung damaging exposures. This new technique is essential to employee health monitoring programs.

Traditional air sampling method for the collection only provides average (TWA) exposures and does not provide a visual time profile of the exposure. The new HAZ-DUST “V” method utilizes the VDM-7500 to overcome traditional limitations. The integration of video coupled with real-time particulate exposure measurements allows a more dynamic assessment in identifying and analyzing the contamination of air. Thus allowing for better control and documentation for improved decision-making.


  • Completely digital and wireless
  •  Real-time video and dust readings of any type of aerosol
  •  Record to disk feature allows for visual proof of any exposure
  •  True breathing zone measurements and size selective air sampling
  •  Allows for concurrent filter samples for further analysis
  •  Compact and rapidly deployable system that is easy to use

Allows both visual and direct readings of lung damaging dust exposure.
