About

• Portability: Small and lightweight, often housed in a compact case, and sometimes battery-powered for use in various locations.
• Sampling mechanism: Uses a pump to draw air and collects particles on a filter. Some samplers can also separate particles by size (e.g., respirable vs. larger particles).
• Flow control: Includes a pump, a rotameter, and a pinch valve to precisely adjust and maintain a constant flow rate during sampling.
• Timer and display: Features a digital display timer and microcontroller-based functionality for setting and automatically running the sampling process for a programmed duration.
• Data analysis: The collected particles on the filter are analyzed to quantify dust levels, measure pollutants like SO2 and NOx, or assess a wide range of airborne contaminants.
• Purpose: Used to assess general air quality, monitor personal exposure for workers, identify pollution sources, and verify that control measures are working effectively.

• Monitoring dust levels at construction sites or in manufacturing plants to ensure compliance with safety regulations.
• Assessing personal exposure of workers to hazardous dust to prevent respiratory problems and other health issues.
• Checking general background levels of air pollution in different environments.
• Evaluating the effectiveness of pollution control measures in a facility.
