Tanvir Khan

Not sure what you mean by 'best'. Are you interested in high accuracy? And, What are you interested in measuring/monitoring?

Maohui Luo

What kind of parameters you want to measure? I think you can get more specific answers if your question can be more detail described.

Ahmed Lotfi Slimani

You can build your own device by using an arduino micro-controller and some accurate sensors like DHT 22.

Best regards

Amiraslan Darvish

The IAQ factors include volatile organic compounds (VOCs), carbon dioxide (CO2), relative humidity (RH), airborne fungi, airborne bacteria, endotoxin and so on. What parameter do you mean?

Deshan Ruvinda Charith Perera

Tanvir Khan Yes I meant by best the high accuracy and approved device. I want to measure O3, VOCs, NOx, SO2, pm2.5/PM10, CO, CO2.

Maohui Luo I want to measure O3, VOCs, NOx, SO2, PM2.5/PM10, CO, CO2. I want to do a research by measuring the above parameters. I want to know the approved and high accurate device.

Ahmed Lotfi Slimani I don't about that technology. Any links I can get a idea about it ? thanks

Amiraslan Darvish I want to measure O3, VOCs, NOx, SO2, PM2.5/PM10, CO, CO2

Elson Galvão

I want to measure O3, VOCs, NOx, SO2, PM2.5/PM10, CO, CO2. I want to do a research by measuring the above parameters. I want to know the approved and high accurate device.

Malek Alaouie

Deshan Ruvinda Charith Perera I personally use Graywolf Sensing IQ-610 for RH%, CO2,CO, O3 and TVOC. TG-510 for SO2, NO, NO2. Andersen N6 sampler for microbiological air sampling. TSI Dusttrak for PM10 and PM 2.5

Thanks a lot. Malek Alaouie Thanks a lot for sharing. Are you a researcher or working related to air quality monitoring ?

All the methods in that like related to ambient air quality. Am I correct ? I want the USEPA method or world accepted standards for Indoor Air quality ?

My pleasure. I am certified indoor environmentalist and a 2nd year PhD student at Brunel University London.
