User's Manual
tCheck makes it easy to measure the potency of your infused oils and create recipes
with exactly the strength that you need. With the addition of the flower & concentrate
testing kit, you can also use tCheck 2 to measure the potency of your plant material** &
concentrates.
tCheck's patented technology measures infusions in:
● Ghee / Clarified Butter
● Olive Oil
● Coconut Oil / MCT Oil
● Alcohol
Oils such as coconut oil and butter must be warmed to a clear liquid state before
measurements can be performed. Do not place the tray on a hot surface, or in the
microwave. Excessive heat can cloud the tray or damage the surface. Boiling
liquids may damage the tray.
When measuring butter, please be sure to only use the clear butter fats. Milk solids will
throw off the measurements.
Mobile App
tCheck2 requires Bluetooth Low Energy (BLE) connectivity to a mobile device in order
to function. Apps are available for both iOS and Android. Please download the apps
from the respective apps stores.

  • Page 3: Interpreting Your Results

    Due to the physics that tCheck uses to make measurements, there are certain limits to what it can measure. This is like using a ruler to measure the length of a dinner table.

    ● Do not wash sample tray in dishwasher, high temperature water will deform the plastic. ● Never store a used tray or clean tray in the tCheck unit. Always remove the tray and store both the tray and tCheck in a clean, dry place. Try to keep your tCheck device free of internal dust as well.
  • Page 5: Troubleshooting

    The given result has an error of ±10%. This means that a reading of 10 mg/ml could have an actual value ranging between 9-11 mg/ml. With proper use, and following all directions, your tCheck should never test outside of this range. Most labs test at a +/- 5% variance.
  • Page 6: Rf Exposure Compliance

    While exposure is unlikely, avoid placing your eye against the sample tray slot opening during device operation. ● If you do not plan on using tCheck for an extended period of time, we recommend removing the batteries to prevent leakage.
