tCheck 3 Potency Tester with Flower Expansion Kit - Instant UV Results

Our review of the tCheck 3 Potency Tester finds it best suited to home edible makers and small growers who want fast, lab-like potency feedback without sending samples out for HPLC. The single biggest reason to buy is its app-controlled UV spectrometer measurement that translates readings into practical dosing units like mg per teaspoon or mg per mL in seconds, letting users confirm infused oil strength or estimate flower percentage on the spot.

Key Features

• App-controlled operation: The connected app displays potency in mg per teaspoon, mg per tablespoon, or mg per mL so dosing an edible recipe is straightforward.
• UV spectrometer technology: Instant measurements use UV spectrometry to approximate potency with lab-grade intent for oils and flowers.
• Flower testing expansion: The included tray and reagents let growers weigh dried buds, mix with reagent, and read percent strength in under 10 minutes.
• Recipe calculator and log: Built-in calculations tell you how much infused oil to blend with uninfused oil and the log stores prior measurements and notes.
• Comprehensive kit contents: The expansion kit includes reusable tray, scale, reagents, filters, syringes, sample containers, oil spoons, a swizzle stick, and batteries so testing is portable and self-contained.

Who It's For

The tCheck 3 is aimed at edible makers who need to confirm activated infusion strength and precisely dose home-baked goods, and at hobby growers who want a quick percent strength estimate for dried flower. Its strengths are practical dosing units, a compact workflow, and a portable kit that contains most consumables needed to run tests at home.

It is less suitable for users who require certified laboratory reports or those testing FECO and RSO, which the product does not support. Professionals needing official, regulatory-grade HPLC certificates should still rely on accredited labs rather than a home spectrometer.

Pros & Cons

Pros

• Provides rapid potency readouts in user-friendly units, making edible dosing easier.
• Portable, app-controlled workflow with built-in calculator and measurement log for recipe tracking.
• Comes as a complete expansion kit with reagents, filters, syringes, tray, and scale for immediate use.

Cons

• Accuracy and ease of use received mixed customer feedback, so beginners may encounter a learning curve or variable results.
• Not designed for FECO or RSO testing and not a substitute for lab-certified HPLC reports when documentation is required.

Our Verdict

The tCheck 3 Potency Tester with Flower Expansion Kit is a good value for home edible makers and small growers who need quick, practical potency estimates and recipe-calculated dosing without lab visits. It is portable and well stocked, but those needing certified lab results or testing FECO/RSO should look elsewhere. For hobby use it brings useful functionality at a reasonable cost.
