That video was about the most unscientific "proof" ever. Like others have said, its a cheap tester with a lot of bad reviews on Amazon. Even if the reading is accurate though, Who is to say there isn't something else in the room causing it?

True, that's why I feel more tests need to be done with other Antminers and other sensors. However, someone else seems to have tested and got similar results.

"it appears that this may be true.

I went ahead and purchased my own HCHO meter (this is the model: http://a.co/6JzJ4ML) to verify after reading this post yesterday.

Here are the results of ~30 minutes of testing next to one of my A3 units:
