Personal Dust Sampler

A Personal Dust Sampler (PDS) is a portable device used to measure airborne dust concentrations in a worker’s breathing zone, ensuring occupational exposure assessment. It is lightweight and worn close to the body, typically clipped to clothing near the breathing area. The sampler draws air through a filter at a controlled flow rate using a small pump. Dust particles are collected on the filter, which is later analyzed in a laboratory to determine the mass concentration of respirable or total dust.

The device often includes components such as a pump, flow meter, filter holder, and cyclone (for respirable dust separation). By simulating actual inhalation exposure, the PDS provides reliable data for workplace health monitoring. It is widely used in industries like mining, construction, textiles, and manufacturing, where workers are exposed to hazardous dust. Results from the sampler help evaluate compliance with permissible exposure limits (PELs) and guide protective control measures.
