tCheck makes it easy to measure the potency of your infused oils and create recipes with exactly the strength that you need.

CBV Calculator

tCheck’s patented technology measures infusions in:

  • Ghee / Clarified Butter
  • Olive Oil
  • Coconut Oil
  • Alcohol

Oils such as coconut oil and butter must be warmed to a clear liquid state before measurements can be performed.

When measuring butter, please be sure to only use the clear butter fats. Milk solids will throw off the measurements.

 

How to run a test

Ensure the sample tray is not inserted into device when powering on.

Place tCheck on a flat level surface and turn on by pressing the black power button.  

  1. Open the sample tray by separating the top and bottom halves.
  2. The top half can be identified by the tCheck logo, put this aside for now.
  3. Place the bottom half of the test tray on a level surface, place a few drops of infused oil into the circular well area.
  4. Now place the top half of the tray onto the bottom, it’s OK if a small amount overflows out of the circular well area.
  5. Ensure that there are no bubbles in the circular well area.

If you are experiencing issues with excess bubbles try reseating the top tray by lifting it slightly from and placing it back down.

Ensure that the excess oil stays within the overflow area and does not flow out of the tray.

Insert sample tray into device then select:  

“RUN A TEST”

Follow the on-screen instructions.

When the test is complete, remove tray and wash with dish soap and warm water.

Only use the soft side of a sponge. Abrasive cleansers or scouring pad will damage the tray.

To turn off the device, press and hold the power button for 5 seconds.

The device will also automatically power off after 5 minutes of inactivity.

 

Interpreting your results

After the test is complete, your results will be displayed in mg/ml.

You can now take your test results and use them in the CBV Calculator to adjust your recipe accordingly

Result displayed as OVER means infused potency is stronger than tCheck is able to measure. To determine the strength you must draw a measured quantity of infused oil, Mix with exact equal quantity of un-infused base oil and perform measurement. Double the result shown by tCheck will give you the measurement of the original infused oil.

 

If you get OVER (Dilution):

Due to the physics that tCheck uses to make measurements, there are certain limits to what it can measure. The analogy is using a ruler to measure the length of a dinner table. With a bit of care, it can be done with a reasonable degree of accuracy.

The procedure is:

Step 1 Measure out a volume of your infused oil

Step 2 Measure out an equal quantity of un-infused oil

Step 3 Mix thoroughly

Step 4 Use tCheck to measure the potency of the diluted solution

Step 5 Multiply the measurement reading by 2
