I have been given the pleasure to test the tCheck 2 here at the house. This item has the potential to show me everything from flower to my coconut oils that i use to make baked goods. The Device. As of right now i have done a few tests and am working with the engineering department with my results. It seems that the infusions, (coconut oil and tincture) are coming out close to desired THC. The one thing that i am seeing the largest difference on is the flower aspect of the device. I have local lab tested (industry testing) strains that were tested at 19-21% and 27-29% thc. When tested in the tCheck the same flower tested as follows. Anvil Lab test 19-21% - tCheck 11-12% Royal Kush 27-29% - tCheck 14-15% The book calls for a 10% +/- but that is a little off. I have provided my results to the team and am awaiting a response. Stay tuned for results and to see what comes of the testing.
