Weather Underground’s Next Frontier: Air Quality

No reason to feel victimized, you can get a 2.5/10 particulate counter suitable for lower temperatures, the e-bam, meets EPA and handles -30 Deg C to 50 Deg C. Starts around $20K.

Nikko Not sure where you get your info about Alaska Temps but we are talking about -40 and greater. I have talked to the local air quality guys in Fairbanks who uses these high price machines and they say the same thing. When the temps drop the data goes kaput as the machine can not do what they have to do when you need the data the most at -40 F, -50 F and -60 F. So why buy an 28K machine that also does not work. By the way Masters was a bit surprise when I mention the operating range to him.
