Why you need ColorGuard

In roast colour measurement, small deviations matter. Temperature changes, ambient lighting and normal sensor drift can shift a reading even when the coffee is exactly the same. Without a fixed reference, you can't tell whether your roast profile changed or just the instrument.

ColorGuard gives your DiFluid Omix analyser a fixed, known reference target. Calibrate against it before each session to rule out instrument drift and see only the real differences in your coffee.

Key features

Who it's for

• Roasters who need consistent, repeatable QC results for every batch.

How to use

1. Keep the card clean and free of fingerprints and coffee dust.
2. Before each measuring session, run the Omix colour calibration using ColorGuard, following DiFluid's instructions.
3. Carry on measuring, knowing the reading reflects your coffee, not the instrument.
4. After use, store the card away from direct sunlight to keep the reference colours stable.

Pair it with the DiFluid Omix analyser for complete moisture, density, water activity and roast colour analysis, from green bean to ground coffee.
