Real-time dust monitor CEL 712 Microdust PRO

Casella CEL introduces the CEL-712 Microdust Pro™ monitor - a small, rugged hand-held instrument that measures concentration of inhalable and respirable dusts, aerosols or powders in real-time, for display on its high contrast color LCD. With a wide detection range (0.001 to 25,000 mg/m3 ) and full datalogging, it is an ideal tool for performing risk assessment in the workplace, analyzing process related dust emissions and performing plant-wide area surveys of dust or aerosol concentrations.
Casella is a pioneer in the use of this technology for process, environmental, industrial hygiene and safety engineering applications, and has delivered proven monitoring solutions to industries ranging across pharmaceutical, bio-test, chemical, quarrying, building material and many other sectors.
Whether used independently to measure material handling processes or to capture particulate releasing events (bag breaks, process vessel access, or loading/unloading operations for example) or paired with a cyclone, filter cassette and sample pump for size selective or gravimetric monitoring, the CEL-712 has a full range of capabilities for solving the toughest applications. Employing a laser diode based light-scattering sensor technology, the battery powered CEL-712 accepts material-specific correction factors and is easily field calibrated with its optical reference cell (included). The CEL-712 also provides proportional output voltage and data stream interfaces.
For use with a sampling pump in short-term stationary monitoring applications, the 'Dust Detective' enclosure is ideally suited for locating the system in harsh environments and unattended operation. The Microdust™ (in combination with the Casella Tuff™ sampling pump) will draw a known sample volume over time across the optical detection cell to allow correlation to gravimetric or size-specific (PM10, PM2.5, respirable) physical sample collection results.

Some of the many applications for the Microdust include:

• Workplace Risk assessment;
  
• Industrial process monitoring;
• Air filtration efficiency testing;
• Environmental dust measurements;
• Boundary monitoring for construction and demolition;
• Leak location in material handling or processing operations;
• Site boundary dust monitoring and environmental/nuisance measurements;
• Industrial process monitoring and control;
• Inhalation Toxicology and other general aerosol research studies.
