Description
Brightness and colorimeter
Code: N.306.xx
Use
For determining the optical properties such as brightness, opacity, fluorescence, color, color differences and whiteness of fabric, paper, cardboard and similar materials.
Device description
The spectrophotometer is a modern, user-friendly and versatile color and whiteness measuring device that is ideal for use in the paper and packaging industry. The device contains key figures, tolerance calculations and diagrams for the D65, C and UV light sources. The measured values can be saved directly to the computer or exported via the network and USB port. The specially developed software is intuitive to use and is based on Windows. Control and calibration of the device: light source filtered by D65, C and UV, management of samples and standard library.
