UPDATED 03-19-19

The tCheck 2 has finally arrived! We put it through a few tests and the full results are below. Don’t have time? Here’s a summary! The tCheck 2 is a portable spectrometer which will tell you the CBV% (cannabinoids by volume) of your oil or alcohol based cannabis infusions. It has a maximum reading ability of 15mg/ml, so you may need to dilute your oil or tincture before testing. As long as you follow the guide and understand its limitations, the device is amazing! If you make your own oils, tinctures, or concentrates you simply MUST have one of these in your toolkit!

POTENCY TESTING

When you are making Cannabutter or infusing Coconut or any other type of oils, one of the main issues home cannabis infusers must deal with is trying to accurately determine the THC and/or CBD content of their products. Some relatively simple math will get you in the ballpark, but what if you wanted to know the exact percentage of cannabinoids present in your infusion?

LABORATORY ANALYSIS

Typically, the only way for you to determine your potency is sending samples of your medicine to a laboratory for analysis. Without access to a lab, you were pretty much stuck using the crude mathematical method to estimate your potency until now! Thanks to modern technology, you now can perform an exact measurement of the cannabinoids of your infusion (or your flower or concentrates for that matter) in the comfort of your own home with a simple inexpensive device called the tCheck!

THE ALTERNATIVE

The tCheck 2 is an application specific UV-Vis spectrometer designed to measure the concentration of herbal compounds in liquids. It works by shining a specific wavelength (color) of light through the oil, then measuring the amount of light that makes it through. The tCheck 2 also has the ability to test your raw cannabis flower and cannabis concentrates! The entire testing process takes place in under 60 seconds and displays total cannabinoids in CBV (Compound by volume) measurement.

EASY TO USE

The tCheck 2 is a simple easy to use device consisting of a small hard plastic box emblazoned with the tCheck logo and a solitary power button. There is a large rectangular slot next to that lonely button which serves to guide in the sample tray to the magic inside. The tCheck 2 sample tray has a small well in the end where you put your good stuff.

To get prepared, first download and install the tCheck 2 App on your phone and connect the device via Bluetooth. Open the App and register your account. This will allow you to see and save the results log of all your tests. Sign in the App and power on the device. Perform any firmware updates if prompted

OPERATION

Prepare your sample *See Below. Load the tray’s sample well with 4-5 drops of your oil or tincture and snap on the lid. (It’s ok if a small amount spills over, the tray will catch the rest.) Make certain there are no bubbles present, nor any solid contaminants as they will make your reading fail.

Power on the tCheck 2 and open the App. On the home page, hit the “Run Test” button. Follow the prompts and have your room temperature available – you need it. After inserting your slide, your test should be finished in about 60 seconds. The device entertains you along the way with a flourish of funny little anecdotes, so you don’t get bored.

Once complete, the results are displayed as either THC or CBD along with the strength in mg/mL.  If you did not have to dilute your product first, this is your final measurement of the cannabinoid content. If you had to dilute, simply multiply your results times the dilution ratio you chose. (Ex. If you used a 1:10 dilution ratio for the test, multiply your results by 10 to get your actual values). The device shows you the CBV % by default. 

You can also test flower and concentrates with the optional Flower & Concentrate Kit. This kit allows for proper sample preparation to allow your tCheck 2 to accurately determine the cannabinoid percentages. The resulting tincture sample is tested in the same manner as any other test, just choose “Alcohol” as your base in the prompts.

SAMPLE PREPARATION

This is the only part where you have to do some work. You must first prepare your sample so that you are reasonably certain it falls under the 15 mg/mL testing limit. As you probably have no idea what you have, this can be a stab in the dark.

For quick easy math purposes, you could start with a 1:10 dilution ratio. Here you will mix 1 drop of your infused oil with 9 drops of your base oil (ie. If you infused olive oil, use regular olive oil to dilute). Mix gently but thoroughly, taking care not to make any bubbles. This is the solution you will test.

If it shows a reading, multiply that result by 10 to get the true strength of your infusion. If it says OVER, don’t worry, that just means you’ve got some stronger stuff! You can try again with a higher ratio like 1:20 (1 part infused, 19 parts base). Multiply your results by 20 to get the true strength of your infusion.

It only takes a few tries to get the hang of this; It’s not a very complicated process. You would get a more consistent result by using the Serial Mixing technique, but this is way faster, way easier, and close enough if you mix well.

The tCheck does require that your solution be as free from contaminants as possible in order to provide the most accurate results. I highly recommend that you filter your material before testing, even if there is no contamination visible at all. The simplest and easiest method for filtering is to use a 150ml disposible syringe and a 20 micron syringe filter.

FINAL THOUGHTS

I think that the tCheck 2 is probably one of the most important devices that a cannabis consumer should own. If you make your own oils for edibles or tinctures, the tCheck 2 takes the guesswork out of the picture and gives you piece of mind by accurately determining your dosage. There may be a small learning curve for some, (mostly with the dilutions is my guess), but most people should have no real issues operating this device; just follow the guides.

The tCheck 2 is available for $279.00 (- $25 with coupon below) directly from tCheck.meIf you wish to test flower, there is an addon kit that provides you with that ability as well. The kit is also available at tcheck.me

If you make oils, tinctures or concentrates at home, you really need to add the tCheck2 to your arsenal! Without a tCheck2, you are just blindly guessing about what you are about to consume….and that’s a recipe for disaster!

Can it test RSO oil? I make my own oils and I want to see how much THC each batch it has in it. I use alcohol (everclear) and a random mix of strains usually what I have around at the time so I never know what I end up with. First batch I made a grain of rice size drop smeared on a cracker was a nice pleasant warm buzz for maybe 6 hours. Second batch the same size drop had me so fucked up I couldnt move my legs for what seemed like an eternity. lucky it was… Read more »

Hi Deb! Yes, the tCheck can test your homemade RSO, you just have to properly prepare your sample first. You will need to perform the above mentioned dilution steps with your oil before testing. Concentrates are typically much stronger, so you may have to perform a much higher dilution ratio like 30:1 or even 40:1. Use the same type of alcohol you used in preparation to dilute your oil, test it and then do the math to see the THC content in your RSO. You do not need to buy the expansion kit, all you need is a medicine dropper… Read more »

Deb, make sure you filter your RSO/Alcohol mixture if your RSO is really dark in color. The better you can filter it the more accurate your results will be. I use a 20 micron syringe filter as mentioned here to make sure there’s no floaties in the mix. You will be surprised how much yuck gets filtered out.

I bought the tcheck based on your original review, thanks for updating this because you answered a few lingering questions I still had. I wasn’t understanding the dilution part so everything kept saying OVER. I go frustrated and put it in my desk drawer where I forgot about it. A few days ago I was going through my drawer and found it so I figured Id give it one more shot to get it working before returning it. I googled to refresh my memory on how to operate it and ran into your article again. Now you have instructions! I… Read more »

I’m happy to see that you figured it out, would have been a shame to return it 🙂 I think that as long as you are aware that there may (will) be work on your part in order to get accurate results, the tCheck is an awesome little machine! Proper sample preparation is key to ensuring a good test. This is the only part of’ the process that can be challenging, but once you figure it out everything works great. As far as the trays go, it looks like the sample wells are mostly recessed enough to avoid being scratched,… Read more »

that thing is such bullshit it cant test flower at all I ground it fine as hell and it still wont read it .

Jack

🤔🤔🤔 did you just put ground weed on the tray??? You do know you have to soak in alcohol first right?

admin
Admin

Hi Mercedes, I’m not sure if you mean you ground your flower finely before performing the required alcohol extraction or if you did what jack said and just put the ground flower on the tray. If its the latter, that will not work as this device only measures things in liquid form. If you did the alcohol extraction and are still having issues try NOT grinding the flower. This will leave you with a much cleaner product to test without all that ground up plant matter contaminating the sample. If your alcohol extraction is cloudy, filtering it will help immensely.… Read more »

Will this test oil that I currently buy from a store? I really want to know if I am getting what they say I am?

Does this read MCT oil? If I buy one and it says “over”, what is a good dilution target to start out with?

admin
Admin

Yes Jon it does read MCT oil. For easy math purposes, I would start with a 10:1 dilution, Increasing if still over. I think 10:1 covers most products well. Just ensure you dilute with fresh MCT oil. Sorry for the late reply, just saw this post.

Does this read MCT oil and if it has to be diluted, what is a good start point for dilution?

yes, it reads mct oil, I just made a batch 3.5 grams of weed (decarbed) infused into 50ml mct oil and extracted 35ml which ended up 28.8mg/ml. I mixed 1 drop of extract to 5 drops of mct oil, the t-check read 4.8mg/ml x 6 drops = 28.8mg/ml

hi allan
I have a question i tested some CBD oil from Hemp Bombs on the t-check-2 just for fun and the test results showed 6.6mg/ml 100%thc, why did it not say 100% cbd? thanks

hi allan
do you know anything about the nova decarb gadget, cause for about 6 months now I been using it to decarb and infuse, started with 10mg nothing 20mg nothing 30mg 50mg 75 and just tried 100mg and still nothing. I was just wondering if its not decarbing good enough, since the t-check-2 cant really tell if is thca or thc so when it says 100% thc that part is kind of miss leading. any thoughts thanks

I had a Nova but im not sure mine worked right it seemd to never decarb fully I had to eat twice as much as when I made it in my oven. at least it didn’t smell like the oven though lol

Don’t even think about buying this piece of garbage. Very very inaccurate, I tested the same flower 10 times and got 10 different readings, all over the board. The flowers kit is a joke, the scale is worth about $5 they give you some cheap tools, 4 oz of 99% rubbing alcohol, and that’s it. $10 worth of stuff and they charge $200 OMG I was so disappointed, then I got pissed cause they think were a bunch of fools. Remember, prior to purchase, you were told!!

Just my 2 cents. My experience with flower testing was also weird, bad and ugly until I tried the syringe filters. I could see really fine weed dust in the alcohol which im sure was throwing off the test. on the other note I also thought $200 was a bit steep for that flower test kit so I didn’t buy it. (my thought was that people would see what the kit had in it and decide not buy it, guess I was wrong.) I use my own supplies and it works just fine. personally I enjoy my tcheck it works… Read more »

I’m quite confused from reading the posts. I purchased a tCheck2 a few months ago and have had problems with the readings. The support staff at tCheck had me trying various fixes and then most recently told me that it only works with isolate infused oil, so my infusions made with decarbed flower would not work. It seems from the posts here that people are getting accurate readings from infusions that aren’t using an isolate. Not sure if it’s me, the tCheck is a scam, or the support staff don’t know what they’re talking about.

admin

Hi Deb! Normal oil infusions made with decarbed flower work just fine as long as you make sure the following is true: #1: You are using Olive Oil, Coconut Oil, MCT oil or clarified butter. #2: You have properly filtered the infused oil. Typically the issue lies with #2, and I have found that proper filtration is mandatory for getting a good consistent reading. I cannot comment on your oil specifically, but I will say that the vast majority of homemade oils that I have come across are extremely dirty. Particulate matter in the oil sample, whether visible or not,… Read more »

I just want to comment that you are right about that need to filter your oil. I was having a hell of a time getting a consistent reading on my extractions until I read your article and the comments here. I almost trashed it I was so upset. I bought those syringe filters from amazon as a last ditch effort and you were right it makes all the difference, it works right now! If anyone is having weird reading on their tcheck get some filters like he says and it’ll all be good. But if you still want to throw… Read more »
