Product Overview
The L-Type Intelligent Medium-Flow Particulate Matter Sampler uses the filter-weighing method to collect airborne particulate matter, including Total Suspended Particulates (TSP), PM10, and PM2.5. It offers stable performance and easy operation, featuring a high-performance built-in lithium battery for long-duration continuous sampling. This instrument is widely used in environmental monitoring, occupational health, scientific research, and educational applications for routine aerosol measurement.
Working Principle
Airborne particles are collected on a filter membrane, then quantified using gravimetric or mass measurement methods. A built-in brushless fan provides a stable airflow, while real-time monitoring of air pressure and temperature allows the flow control system to automatically compensate for deviations, ensuring accurate sampling. Data can be exported or printed via USB or Bluetooth, maintaining a complete and reliable record.
Key Features
- Low Noise, High Load: Brushless fan design reduces noise and supports long-term continuous operation.
- Automatic Recovery: In case of power interruption, the sampler remembers its state and resumes sampling once power is restored.
- Precise Flow Control: Real-time monitoring of pressure and temperature with automatic flow compensation enhances measurement accuracy.
- Long Battery Life: Equipped with a 32 Ah high-capacity lithium battery for extended, stable operation.
- Data Storage and Export: USB data export and Bluetooth printing simplify field reporting and data management.
Applications
- Environmental Monitoring: Continuous collection of TSP, PM10, and PM2.5 for air quality assessment.
- Air Quality Management: Provides data to evaluate particulate pollution and guide air quality improvement measures.
- Scientific Research: Supports studies on air pollution, particulate source analysis, and other aerosol research projects.
- Public Health Monitoring: Assesses the health impact of particulate matter on human populations.
- Emergency Response: Enables rapid, reliable sampling during sudden air pollution events, supporting timely decision-making.
