DiFluid ColorGuard Calibration Card for Omni

The DiFluid ColourGuard Calibration Card for Omni is a precision reference accessory designed to maintain the accuracy and consistency of coffee roast colour measurements when using the DiFluid Omni system. It provides a stable, standardised colour target that allows users to calibrate the device before analysis, helping ensure that readings are consistent across sessions, environments, and devices.

By minimising variation caused by lighting conditions or sensor drift, it helps roasters and quality control professionals trust that differences in readings reflect real changes in roast development rather than measurement error. Designed for use within the DiFluid tool ecosystem, the ColourGuard card is a simple yet essential step in a professional coffee analysis workflow.

It integrates seamlessly into routine calibration procedures and supports repeatable, data-driven roast evaluation. The compact and portable design makes it ideal for use in both commercial roasteries and laboratory environments.
