The color sphere spectrophotometer is a highly reliable device with 45° / 0° geometry and circular illumination. It measures with the same accuracy both rough, direction-dependent surfaces, granules or powders (such as plastic concentrates and resins), as well as smooth, uniform surfaces (such as varnish layers). A white standard or zero standard (black) serves as a reference.

Special Features of the Device:

• Fast measurement without heating the samples
• Interchangeable screens for samples of different sizes
• Simultaneous determination of gloss and color
   

Application Examples:

• Monitoring yellowing in plastics
• Quality control of standardized, colored paints
• Measurement of color changes due to stress
