Real-time, respirable, personal dust monitor designed specifically for U.S. based mining applications and the only CPDM designed to meet the latest requirements of the MSHA Dust Rule.

Engineered for timely, high-quality personal dust exposure information, the PDM3700 monitor protects miners’ health by tracking the shift-average respirable coal dust exposure as it approaches regulatory limits. Providing mine workers and management with the tools for personal coal dust monitoring and reducing their exposure, the PDM3700 real time dust monitor is the first line of defense in preventing long-term health effects.
 

The PDM3700 monitor provides three primary, real-time measurements: primary current mass concentration, primary cumulative mass concentration and percent of limit. Two secondary user-initiated measurements are also available and can be performed without interfering with the primary sample. The battery operated PDM3700 starts by drawing a continuous sample of air from the breathing zone. It then removes any particles that are larger than respirable in size and measures the mass of the dust, which is collected on an exchangeable filter.
 

Dust exposure results are automatically computed, eliminating the need for filter transport and handling steps connected with the manual gravimetric method. This automatic method leads to a significantly lower per-sample cost then with manual sampling and has the added benefit of continuous information availability.

Designed for the Mine Environment

Proven underground capable, through the success of the PDM3600 monitor, the PDM3700 personal dust monitor also offers accurate, continuous, personal respirable dust exposure information. Capable of satisfying the typical mine environment, the durable, belt-mounted case is made of static dissipating housing.
