Your advantages at a glance
The perfect solution for laboratory & production
-
Many measuring openings
Various measuring openings (10 mm, 13 mm, 19 mm, 25.4 mm, 31.8 mm) for many types of samples. -
Compact dimensions
With a weight of 4.5 kg and dimensions of 16.0 cm (height), 13.0 cm (width) and 36.0 cm (depth), the CFEZ is the ideal partner in the laboratory and production. -
Integrated QC software
Display of absolute and differential data, colour location visualization, spectral curves, spectral data and PASS/FAIL with individual tolerances.
-
45°/0° geometry
The CFEZ measures colour as the human eye sees it. Every day. Reliable and precise. -
In many versions
The ColorFlex EZ is available in Tomato, Citrus and Coffee versions. -
Uncomplicated & precise
Simple measurement at the touch of a button with measurement results within a few seconds. Reduces training time, optimizes the workflow and increases your productivity.
Stand-alone colorimetric station
The fully sealed system guarantees precise results for many years. Dirt, dust and liquids cannot get inside – this makes the system the ideal colorimeter, even in harsh production environments.
Measure colour as the eye sees it
With the ColorFlex®EZ, the illumination is circular around the sample at 45° – this ensures that the sample is illuminated as homogeneously as possible. This DIN standardized method corresponds best to the visual colour impression of our human eye. 45°/0° and 0°/45° are therefore usually considered when the overall impression (appearance) of a particular colour is to be measured.
