Ambient Air Comprehensive Sampler

Product Introduction

The Environmental Air Integrated Sampler is an instrument dedicated to collecting atmospheric pollutant samples. It can simultaneously capture particulate matter (such as TSP, PM10 and PM2.5) and gaseous pollutants (such as harmful gases and VOCs), enriching these pollutants onto carriers such as filter membranes, absorption liquid or adsorption tubes by physical or chemical methods for subsequent analysis of pollutant concentration, particle size distribution and composition. It is widely used in environmental monitoring, health and epidemic prevention, industrial and mining enterprises and scientific research institutions, providing a key data basis for air quality assessment, pollution prevention and health protection.

Application Range

• Ambient air detection: environmental monitoring stations at all levels, atmospheric background monitoring points, and air quality monitoring in industrial parks.
• Scientific research: meteorological research, atmospheric chemical composition analysis, and sampling for environmental impact assessment.
• Occupational health: fixed-point sampling and detection of toxic and harmful substances in workplace air.

Product Features

1. Simultaneous gas-solid collection: supports simultaneous sampling of particulate matter and gaseous pollutants, capturing particulate matter by the filter-membrane gravimetric method and collecting harmful gases by the solution absorption method, achieving multiple uses in one instrument.
2. Multi-channel independent control: the typical model is equipped with five independent channels (four gas channels and one particulate channel), each of which can be set separately for flexible use in different monitoring requirements.
3. Constant-pressure and cross-flow technology: uses a PID algorithm with compensation to automatically compensate for flow deviation caused by resistance or voltage fluctuation.
4. Automatic compensation of environmental parameters: built-in temperature, humidity and pressure sensors monitor the pre-meter temperature and pressure in real time and automatically calculate the standard-condition volume, improving data comparability.
5. Power-failure protection mechanism: data is automatically saved when sampling is interrupted, and collection can continue after power is restored.
6. Massive storage and export: local storage of more than 100,000 data records, supporting USB flash drive export.
7. Beidou satellite positioning support for high-precision positioning.
