About

A combined dust sampler is

an air quality monitoring instrument that simultaneously collects both airborne particulate matter (

) and gaseous pollutants. It's used in occupational and environmental settings to assess air pollution, ensure compliance with regulations, and conduct research. These samplers work by pulling air through specific collection media, like a filter for particles and a sorbent for gases, to provide a comprehensive analysis in a single operation.

• Simultaneous sampling: Collects both solid particles and gaseous contaminants at the same time, making the process more efficient.
• Particulate matter collection: Uses a cyclone separator and filters to separate and collect different size fractions of dust, such as

  (respirable dust) and

  (fine dust).
• Gaseous pollutant monitoring: Can be equipped with an attachment to sample gases like sulfur dioxide (

  ).
• Accuracy and reliability: Features like a digital flow controller ensure a consistent and accurate flow rate for reliable monitoring.
• Data management: Many models include a digital display for real-time data, a USB data logging function, and are compliant with international standards like CPCB, EPA, and ISO guidelines.
• Portability: Often designed with a weather-resistant and durable body, and can operate on both AC power and a battery backup for field flexibility.

• Industrial hygiene and workplace safety
• Environmental monitoring and research
• Regulatory compliance in industries such as cement, food processing, and mining
• Agricultural monitoring
