Environmental monitors

[TerryOh]

I have been looking for a reliable device to capture indoor and outdoor air pollution.  As many are aware the reports on the reliability of tech merchandise is crappy at best.  Have there been any reviews of such monitors?  I think it would be valuable to many to have reviews of these devices.  There are a plethora of devices, but most of them look like junk.  Some look great but the reviews suggest they are well, "great looking junk".  Some of the data I would like to have is temperature, humidity, CO ppm, Volatile organic compounds (VOC's) - thanks.

you should reach out to a university laboratory.  They will have such things for their exhaust hoods.  You could easily get a brand name from there.
