Air samplers are devices used to collect samples of air for analysis. They help measure the presence of pollutants, allergens, or microorganisms in the atmosphere. By drawing in air through filters or collection media, these devices can capture particles and gases for further examination in laboratories. There are various types of air samplers, including active samplers, which continuously draw air, and passive samplers, which rely on natural air movement. These tools are essential for environmental monitoring, workplace safety, and public health assessments, ensuring that air quality is maintained and potential hazards are identified.
