You should contact Mike Adams in Austin, one of the most informed and honest people I've ever known on these and other environmental poison issues...
http://labs.naturalnews.com ....love 6th street, hope it's still going strong!!!!
We should all get together on this thing and stop it (needless poisons) now!!!
As you can tell I'm totally in support of what netc is doing to combat these problems!
I purchased a Pi/200 combo from them and it's been running years now without probs!
I would click below and order one of these units before they are gone!!!!
https://www.netc.com/bb/viewtopic.php?f=6&t=1259I hope they can offer some more of these monitors as they (Pi/gmc) are (bar none) the most dependable and accurate I've seen so far for overall monitoring...
Tell Mike I said hello and you (and Mike) can contact me (PM me) anytime!!!
