Stand-alone colorimetric station ColorFlex L2
The ColorFlex L2 serves as a stand-alone colorimetric station. The Essentials 2.0 software is intuitive and simplifies operation for all employees. Whether chemicals, pharmaceutical products, foodstuffs, raw materials or plastics, the ColorFlex L2 can be used for a wide range of applications, both in the laboratory and in production.
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 L2, the illumination is circular around the sample at 45° – this ensures the most homogeneous illumination of the sample 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.
The internal components of the ColorFlex L2, such as the high-quality holographic grid, lead to precise and repeatable measurements. Whether the sample is translucent, opaque, liquid, solid or paste-like, sample handling is made easier with matching HunterLab accessories.
