This PM2.5 ambient air sampler delivers accurate and stable particulate matter sampling for air quality monitoring applications. It uses an active flow control system with a digital mass flow controller to maintain precise sampling conditions throughout operation.
The sampler controls PM2.5 sample flow at 15 L/min and coarse particulate flow at 1.67 L/min. It continuously measures and displays the volumetric flow rate in real time, allowing users to monitor performance easily.
An oil-free, non-pulsating vacuum pump ensures stable airflow and long service life. The induction motor and VFD-based flow control unit maintain a consistent pump speed and reduce flow fluctuations. This design improves accuracy and protects internal components.
The system automatically compensates volumetric flow using ambient temperature and barometric pressure sensors. This feature minimizes measurement errors caused by changing environmental conditions.
An integrated data logger and 4×40 LCD provide real-time visibility of key sampling parameters. The sampler records flow rate, ambient temperature, filter temperature, barometric pressure, filter pressure, elapsed sampling time, total sampled volume, and coefficient of variation (CV). Users can store data directly on a USB pen drive.
Operators can select logging intervals from 1 to 60 minutes based on monitoring needs. The built-in real-time clock accurately tracks sampler operating time for each sample run.
The sampler supports manual and automatic operation modes. The automatic mode allows users to preset start and stop times. The system also includes auto shut-off protection that activates during low flow conditions or high filter pressure. This prevents damage and protects sample integrity.
A leak check adaptor simplifies routine leak testing and system verification. The sampler accepts 47 mm filter media, making it compatible with standard laboratory analysis methods.
The unit features PM10 impactor and PM2.5 WINS impactor inlets, designed according to USEPA standards. These inlets ensure reliable size-selective sampling for regulatory and research applications.
This sampler suits industrial sites, environmental monitoring agencies, laboratories, and air quality consultants that require dependable particulate matter measurements.
