WHAT CAN IT MEASURE?
tCheck 2 will be able to measure isolates and winterized concentrates infused in clarified butter, coconut oil, alcohol, and olive oil. With the Expansion Kit, you can test for THCa in raw flower and concentrate.
We measure isolates for CBD and THC infusions in coconut oil (MCT), alcohol and olive oil. We measure THC only in clarified butter, not CBD or THCa.
At this time we do not measure CBD flower directly. Additional oils and base solvents will be added in future module upgrades. Because we add capabilities based on customer demand, please fill out the “wish list” with your vote on the base you want (e.g. VG, honey, grapeseed oil, etc.).
WHAT PHONE DEVICES WILL BE SUPPORTED?
Any phone running iOS 11+ and Android 5.0+ with Bluetooth LE (4.0) support.
ARE THERE CONSUMABLES OR ADDITIONAL COSTS PER TEST?
tCheck 2 is shipped with a re-usable tray. Individual trays are paired with devices. For oil/alcohol infusion tests, there are no additional consumables.
HOW LONG WILL BE AAA BATTERIES LAST?
That depends on how much you use the device. Under normal use conditions, a set of batteries should last 4–6 months.
WHAT KINDS OF BATTERIES CAN IT USE?
Three (3) AAA Alkaline, lithium, and NiMH. Do not use NiCd.
WILL THE tCHECK 2 APP WORK WITH the tCHECK CLASSIC?
No, the tCheck Classic has a screen to control the device. Measurement results will not be automatically imported from the tCheck Classic into the tCheck 2 app.
WILL OTHER BOTANICALS IN THE INFUSION THROW OFF THE MEASUREMENT?
It depends on the botanical. For isolates we recommend that you infuse the material first, test, then infuse the other materials. For flower material, we recommend you test your flower before you decarb and infuse.
WHAT IS CBV?
CBV stands for Compound by Volume. Total aggregated active compounds.
I SEE THAT THERE ARE MEASUREMENT BUTTONS FOR DECARBED AND NON-DECARBED. WHAT IS THE DIFFERENCE?
Various botanicals (THCa (Non-decarbed), THC (Decarbed), CBD (Decarbed)) have different UV absorbencies at each wavelength. The tCheck 2 adjusts the wavelength and intensity of the light to target the botanicals being measured.
DOES IT MEASURE VG, HONEY, HEMP OR OTHER OILS NOT LISTED?
Because the tCheck 2 does not have the ability to measure these oils directly, you can still use the tCheck 2 to achieve a relative potency. The absolute number will not be exact. Use the coconut oil setting to perform your measurements every time and you can compare one batch against another. Please let us know what oils or features you would like added by completing our Feature Request Form.
WHAT DOES THE tCHECK 2 TEST FOR?
THC, THCa, or CBD. Samples measured under the flower or concentrate setting will only be tested for THCa.
HOW ACCURATE IS THE tCHECK 2?
+/- 15% of the reading at full scale. The tCheck 2 provides the results in terms of Milligrams of botanicals per volume of liquid such as milligrams per milliliter. If your result is 15 mg/ml, then the margin of error is +/- 2.25 mg/ml. The repeatability of measurements is also within +/- 15%. Because temperature plays an important role in the accuracy of the measurement, all calibration testing is performed with the device and analyte temperatures at 75°F (24°C). Butter is calibrated at 105°F (40°C).
WHAT IS THE MEASUREMENT RANGE FOR THE tCHECK 2?
1–15mg/ml for decarbed material (THC / CBD) and 1–10mg/ml for non-decarbed material (THCa).
WHAT KIND OF ALCOHOL CAN IT TEST?
The tCheck 2 is calibrated with 99.9% alcohol. Since water absorbs UV, added water will interfere with measurements. Reasonable results can be achieved with alcohol that is 95% or more.
Certain chemical compounds in dark alcohols will skew the reading, so it’s important to make sure that you're using clear-or-light colored alcohol when testing with the tCheck 2.
99.9% Isopropyl alcohol is available to purchase through the tCheck website.
