This is taken from another site regarding the Steephill Quantacanna machines.
By the sounds of it the CDx is a handheld version of a similar type machine. If you can read past all the bullshit pseudo science speak they shine a fancy light at the sample, the sample absorbs light a certain way and it tries to find that in it's database and reports the results from the database rather then the sample. That's my understanding if I am wrong someone can correct me I am sure.
That second bit is laughable, because it's not an actual test for potency it's more accurate .... but it compares to the "less accurate" type of testing that they have recorded in their database. So wait a minute.... IF GC is not accurate or has all these failing points why would they have a database full of GC data that they then relay to the customer... I'm so fucking confused right now.
THIS IS REGARDING THE QUANTACANNA machine. It's more accurate because there is less science and more guess work, I guess.
If I was looking for a portable testing I'd look into the guys making the little vials that change colour, I forget what they are called right now. But they can't be nearly as expensive and they actually test your sample rather then giving you test results from some guys sample in California. They have a THC and CBD test, no idea how accurate they are there are people testing them now I think. I would have more faith in that product. (

I want to see a moldy sample loaded and see if it can at least do that.
