CromlaWatch is used to record color values with sample rates from 0.1 s. The display can be shown either in the three components of a color (Lab) or the color deviation in ΔE. The target color can be recorded and a tolerance can be specified for each color component and also for the total deviation. The tolerance is represented in the diagram by a tolerance tube. If the color tolerance of a component is exceeded, the corresponding field is highlighted in red. The diagram shows when the tolerance threshold has been exceeded. The data can be exported in an Excel-compatible CSV file for documentation purposes. As the measurement rate can vary greatly, the time per data file can be set between 5 minutes and 1 day.
