Compact and Convenient
The tCheck potency testing device was designed for convenience, starting with its size. Every unit is 1.97 x 0.79 x 0.79 inches — no bigger than a retro GameBoy, and far smaller than an HPLC machine that runs $3,000 to $60,000.
tCheck pairs directly to your smartphone. Download the tCheck app, test your product, and always have your results in your pocket — no lab scheduling, no waiting days for results.
Reliable Technology
The definition of reliable is "consistently good in quality or performance; able to be trusted" — and the tCheck devices deliver. Want the data? Read the accuracy breakdown here.
The tCheck testing range covers the full spectrum of home cannabis use: 1–15 mg/ml for infusions, 1–40% for flower, and 1–99% for concentrates. Results display on a simple digital readout — accurate numbers, no interpretation guesswork. The device logs over 1,000+ tests with an unlimited history, so you can track potency across batches over time.
Fast Results
A lack of potency knowledge shouldn't delay your cannabis experience. tCheck delivers results within 2 minutes of testing. With a simple preparation process and an extensive library of testing resources, you can accurately dose, recreationally calibrate, or bake perfectly portioned edibles — every time.
Easy on Your Wallet
tCheck understands the importance of properly dosing prescribed cannabis for physical and mental health. Unlike industry-standard testing machines ranging from $3,000 to $60,000, tCheck gives you the power of potency testing for $399.99 with a guaranteed 6-month warranty. Test as often as you need — the per-test cost drops with every use.
