Well, here's what we did.

We have an employee who used to smoke exhale cigarette smoke into a plastic container which had a small hole in it. We inserted the mercury probe into the hole and took a reading.

The reading was literally off the scale of the device. It was so high that it indicated that we had to put the device into self-cleaning mode and cool down which takes about an hour.

Next, we had the employee stand about 10 feet upwind and exhale smoke while another employee held the device and took samples while smoke blew by. It was windy (about 10 to 15 mph) so the device was only able to catch short bursts of smoke.

We did this to simulate someone standing on a corner, for example, while someone nearby inhaled second-hand smoke.

The readings from this were on the order of the amount of mercury vapor that comes off a can of tuna when it's first opened... quite high (depending on brand of tuna). I don't remember the exact numbers but they are all on the video.

I know that certain dense particulates can interfere with the device measurements so we don't know if the readings we're accurate or not, but it sure makes you want to see some controlled lab tests, especially if you smoke.

I'll work on getting it posted as soon as possible but I know it will probably be a couple weeks if not months.
