Pm2.5 And Tvoc Air Quality Laboratory testing process

       The impact of the new national standard of air purifier on the industry in 2016 (air purifier environmental chamber) The following article is from China Daily

Air purifier CADR experimental chamber P2.5 test process

       The Pm2.5 And Tvoc Air Quality Laboratory testing is an airtight chamber with the standard size of 3.5*3.4*2.5m for the national test regulation standard of 30m³. By continuously lighting five Red Tashan classic 1956 type cigarettes (this cigarette is also the national test standard regulation experimental cigarette, this can be used in the ring instrument of the particle generation device), through the injection port, the occurrence of brick industry of solid particles, extract and inject into the simulation test chamber, and fan stirring 3-4 minutes, is its uniform distribution in the experimental chamber, close the fan, to be fan static.

       Turn on the maximum power gear of the air purifier for air purification work. At the same time, turn on the brick industry instrument for data sampling of space purification rate. During the sampling process of half an hour, the air purifier continuously purifies the air. And we can collect the data by conducting PM2.5/PM10 value test every 2 minutes by the brick industry instrument.

      Subsequently, the formula developed through the testing standards set by the national standards, measured the purification efficiency of the air purifier using the air purifier CADR experimental chamber test air purifier and the CADR value and other performance indicators.

   Analytical instruments for P2.5 are available: TSI aerosol analyzer, and also handheld analyzer.
