PQ200 Environmental Grade Fine Particle Sampler

The PQ200 environmental grade PM2.5 sampler produced by BGI is designed in accordance with the Federal Reference Method (FRM) and is a 'portable sampling' particulate matter sampling system in FRM. The design of PQ200 strictly follows the U.S. National Environmental Air Quality Standards (NAAQS) published on July 18, 1997, to meet the requirement of 24-hour environmental 'fine particulate matter' sampling. BGI has also developed the 'Very Accurate Cyclone Particle Size Sampling Head' (VSCC) to replace the WINS impact sampler, which can achieve a cleaning cycle of every 30 days. Further information can be found in the relevant single page introduction. The existing PQ200 sampling head can be converted.

The PM2.5 (particles with aerodynamic diameter less than 2.5 microns) collected by the instrument was collected at a flow rate of 16.67 LPM through two inertia separators designed according to EPA standards, and a 47 mm PTFE sampling membrane was obtainedAt the same time as real-time sampling, record the ambient temperature and atmospheric pressure. Microprocessors and advanced volumetric flow control systems can ensure continuous collection of sampling data into memory. Record the actual temperature and pressure conditions for 5 minutes simultaneously with the volume flow rate of the sample, the temperature and pressure of the sampling membrane. The identification flags for detecting values and displaying anomalies will be overwritten when the operator downloads sampling data from a laptop. The EPA's sampling and auditing procedures have made PQ200 version A their dedicated sampler. This model of sampler has also become the preferred choice for all officials or individuals who wish to strictly follow EPA regulations for sampling.
