Default Re: Any feedback on the Corentium Pro?

You mentioned tamper resistance, which with the 1027's I used to use that could be an issue. Though I think it's pretty rare.
They are plug in and sizable so they are an easy target for an unscrupulous person.
Just put a bowl over it and you've screwed the results.

One of the things I like about the Corentium's is they are battery powered and very small.
I usually put them up in the basement ceiling framing.
No one would ever know where it is.

I'd get my license revoked if I put a monitor up in the ceiling!

You really want it in the breathing zone. Illinois requires placement to be minimum of 20 inches from the floor, and no more than 6 feet from the floor. IMO if you put it in the ceiling you might as well just test the floor above, you aren't getting a representative sample of the basement that way. My .02

Md goes by EPA guidelines, no state license or protocols.
More than 20" inches above the floor, yes.
In the situation I just described its in the open framing of a low basement ceiling.

Are you saying that you usually place the devices there, or only when you encounter basements with low ceilings?

Though I see your logic in placement location to protect from tampering with the device, you will find that most states with protocols, and most device manufacturers will stipulate that the device should be placed in the breathing zone. Interesting what flies in regulated vs non regulated states.

In Illinois, only the Correntium Pro has been approved for use.

It is one of the locations I place the monitor.
Again there are no state protocols here, so the EPA guidelines are followed.
And there is no state list of approved devices.

This is from the EPA guidelines. Bold is mine.

• The detector should be at least 50 centimeters (20 inches) from the floor, and at least 10
centimeters (four inches) from other objects. For those detectors that may be suspended, an
optimal height is in the general breathing zone, such as two to 2.5 meters (about six to eight
feet) from the floor
.

Just finished my first inspection with the Pro. I felt like it did a great job and produced the accuracy required. It is an approved instrument. Air Things has been very helpful with hardware and software questions. I may end up writing some addition html to augment their software. If you would like to see a report with real data I am happy to make it available. I tried to post it, but got an error, must be to big.
