Applications

EVM Series

Applications

A real-time, direct reading dust monitor is used in many different applications such as walk-through surveys in manufacturing, wood making plants and/or bakery shops, background sampling, site dust measurements, assessment of the effectiveness of dust control systems, and measurement of indoor air quality (IAQ). It is also used to analyze work-place exposure and help identify dust control techniques such as training or implementing engineering controls.

Time history: manufacturing

 Industrial setting - Used to monitor and ensure health and safety in settings where toxic fumes are released

(such as testing levels at a paper mill or a foundry). This information can be used to identify the source and particle concentrations.

 Sick Building syndrome – Used to evaluate air toxins and ensure building standards maintain a comfortable work setting.

 Work site assessments.

 Military applications.

 Outdoor monitoring applications include construction sites/dust outside of mines.

 Regulatory compliance (i.e., OSHA, MSHA, IEC,

ACGIH).

 As a mapping device - Layout a grid of high contaminant areas, and quickly collect sample data at multiple locations to help identify paths and sources, by relative readings.

 As a survey monitor

 Specific area in a plant/facility – used to maintain a quality work environment and conduct area monitoring samples throughout an entire facility.



Specific areas in a plant/facility - used to identify key areas that may be toxic or unsafe and implement acceptable practices such as changes in the ventilation.
