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

The VDM-7500 measures the levels of lung-damaging particulates while simultaneously video taping the workers job task. The work activity can be visualized and linked to the workers dust levels.

The system is designed to be user-friendly and all operations are window-based and easy-to-use.

Being able to actually see, record, and store video and dust data of a worker's lung-damaging exposure is essential to employee health monitoring practice.

HAZ-MAT responds to heavy industrial pollution air monitor program. The integration of video couple to measure particulate contamination allows a more dynamic assent in identifying and analyzing the air contaminant exposure. This allowing for better control and documentation for improving decision-making.

Applications

Determining levels of worker respiratory protection for OSHA compliance
Compliance program reviews
Evaluating work practices and controls of any dust-generating practices
Safety audits
NIOSH Video exposure monitoring for real-time graphical overlays
Welding fume exposures
Air quality studies in occupational health and industrial hygiene
Haz-Mat air quality investigation and waste site remediation
VDM-7500 Monitor is a useful tool for all monitoring applications involving lung-damaging particulates

In addition to Occupational Health applications, the VDM-7500 Video dust monitoring system has benefits for hazardous material remediation, fire fighters, and emergency rescues. Industrial emissions and Insurance company in video documenting any lung-damaging particulate exposure.
