PROWHITE · DS-620
Portable Spectrophotometer
A portable measurement platform for textile colour difference, fastness, whiteness, yellowness and colour strength assessment.
WORKING PRINCIPLE
Controlled laboratory workflow
Measure specimen spectral reflectance using d/8° geometry. SCI and SCE evaluations support colour quality control under the selected illuminant and observer conditions. Standard supply includes Windows colour quality-control software; ColorRecipe is offered separately.
Applications
- Textile colour quality control
- Colour difference and fastness assessment
- Whiteness, yellowness, metamerism and colour strength
