tCheck Cannabis Oil Potency Tester Update

I’ve been writing fewer articles lately, and one of the reasons is that some time ago I started to judge myself more (yeah, I know…I probably need more cannabis!), so now I tend to write longer and more heavily edited articles. So this is my attempt to break that habit.

Last year (wow, is it really that long?) we wrote about the tCheck and did a full product review. We were impressed with the unit itself, but a bit concerned about the accuracy and repeatability of its measurements. We’ve been a bit frustrated since then because we had some testing to do on the Levo Oil Infuser we wrote about a few months ago that didn’t seem to work properly with the tCheck.

Well, if there’s one thing we’re perhaps too good at, it’s patience, but finally tCheck has come through with a software update that actually checks out. It is properly labeled 2.0, because from what we understand it represents a newer approach to calculating THC internally, and it seems to solve the problems we saw before. Hint: if you can’t get the update, try a different WiFi login or a hotspot, apparently their software can be wonky with WiFi.

In particular, the new measurements (of our old products) not only check out with our calculated potencies, but also with published potency for a commercial product. So we’re seeing a number of approaches that verify the results. And apart from coconut oil, we also got results that matched our experiences with infused olive oil as well as Gold Dragon tincture.

The tCheck people are working on all kinds of new good stuff. I’m sure they’re celebrating right now, but the good vibes from getting past this hurdle will hopefully speed up things for their design team!

About Old Hippie Old Hippie is a father of two boys and thankfully living in California where all this kind of thing is legal. He started smoking marijuana in 1967 in high school, experimented with mind-expanding drugs of all kinds, and then straightened out 15 or so years later to become an airplane pilot. After being diagnosed with depression in 2000, he lost his job and most of the following decade to prescription medications (such as antidepressants) which sapped his energy and will. Finally, a chance conversation with a friend led to a doctor’s recommendation for medical marijuana (MMJ). This changed his entire life, health, and outlook for the better. is his continuing story. It’s also his way to provide experienced advice on using medical marijuana effectively and responsibly, as well as advocacy, activism, and support for others. Old Hippie teaches about safe use of cannabis edibles, Canna Caps, vaporizers, dosing, and even microdosing.


Hi old hippie, I really appreciate your reviews. You breaking down the tcheck has been great, as there are few solid reviews out there. Tcheck is set to release their newest model within a few weeks.

They’re selling an additional “expansion kit”, which seems to be a scale, and some type of alcohol, to test rso and other solvent based products. Do you know is the tcheck can test solvent based extracts or how to add a reagent so that the tcheck can do its thing. An additional 150 for the kit is a big ask, curious of your answer.

Thanks a lot
