TCheck 2 Hash Potency Test: 5 Steps to Accurate Results at Home

The TCheck 2 hash potency test lets you measure the THC percentage of your hashish, concentrates, or infusions at home without sending samples to a lab. In this guide we walk through the exact 5-step process used to test a dry hashish sample — which came in at 34% THC — and share tips for getting the most accurate results from your TCheck 2 cannabis tester.

What Is the TCheck 2 Cannabis Tester?

The TCheck 2 is a portable, Bluetooth-enabled cannabis potency meter that works by analyzing a small dissolved sample under UV light. It connects to a smartphone app that guides you through the test, calculates the THC or CBD percentage, and stores your results. It can test flower, hash, infused oils, tinctures, and concentrates — making it one of the most versatile home cannabis testing tools on the market.

For a TCheck 2 hash potency test specifically, you use the isopropyl alcohol hash test method: dissolve a precise amount of hash in 99% isopropyl alcohol, then test the solution with the device. The app does the math.

TCheck 2 Hash Potency Test: 5 Simple Steps

1. Weigh 30–60mg of hash: Use a precision milligram scale (accurate to 0.001g). Weigh out approximately 30–60mg of your hashish. In this test, 36mg of dry hashish was used. Breaking the hash into smaller pieces increases surface area and improves extraction accuracy during the isopropyl alcohol hash test.
2. Draw 10ml of 99% isopropyl alcohol: Use a syringe to measure exactly 10ml of 99% (or 96%) isopropyl alcohol into a small container. Pour it into the TCheck 2 solution bottle with your hash sample. Higher purity alcohol gives more accurate readings — 99.9% is ideal.
3. Shake for 5 minutes: Seal the bottle and shake it vigorously for a full 5 minutes. This dissolves the cannabinoids from the hash into the alcohol. The longer and more thoroughly you shake, the better the extraction and the more accurate your how to test hash potency at home result will be.
4. Prepare the TCheck 2 tray: Open the Bluetooth connection in the TCheck 2 app and select “Run Test.” Open the optical tray, draw 4–5 drops of your hash-alcohol solution into a 1ml syringe, and dispense them onto the filter in the tray. Avoid air bubbles — check the tray under light before inserting.
