- Use fresh, properly stored samples. THC degrades over time; keep buds in a sealed container at 4°C.
- Calibrate regularly. Follow the manufacturer’s schedule to maintain accuracy.
- Take multiple readings. Averaging results reduces random error.
- Maintain a clean workspace. Contaminants can skew results.
- Document each test. Use a spreadsheet or app to track trends over time.
- Follow safety guidelines. Wear gloves when handling oils and solvents.
- Check battery levels. Low power can affect sensor performance.
- Compare with lab results. Periodically validate your home tester against a certified lab.
