About

A Handy Dust Sampler is a portable device used to collect and analyze airborne dust particles for air quality monitoring in both industrial and environmental settings. It works by drawing air through a collection surface like a filter, capturing the particles for later analysis to assess hazards, monitor pollution, and ensure workplace safety. These samplers are compact, often battery-powered, and designed for easy transport and use. 

Key features and functions

• Portability: Designed to be lightweight and compact for use in various locations. Many are battery-powered, allowing for flexible deployment.
• Airflow control: Features a diaphragm pump and a rotameter or other controls to adjust and measure the flow rate of air being sampled.
• Particle collection: Draws air through a collection surface, which can be a filter, membrane, or impinger, to capture dust particles.
• Versatility: Can be used for both particulate and gaseous sampling. Some models have attachments to collect gaseous pollutants like sulfur dioxide and nitrogen oxides alongside dust.
• Timer and operation: Often includes a digital timer for setting sampling duration and a microcontroller for automated operation.
• Analysis: Collected dust can be analyzed through methods such as gravimetric analysis (measuring weight), microscopy, or chemical analysis to determine concentration and composition. 

Applications

• Occupational health: Used by industrial hygienists to monitor worker exposure to hazardous dusts and ensure compliance with safety regulations.
• Environmental monitoring: Utilized by environmental agencies to assess air quality in urban, industrial, and construction areas.
• Pollution control: Helps identify pollution sources and evaluate the effectiveness of control measures.
• Research: Serves as a tool for researchers studying air quality and particle dispersion.
