COLO.Science — BENCHTOP SPECTRO-COLORIMETER FOR POWDER & GRANULES
COLO-R17 — Plastic Masterbatch Colorimeter (Powder / Granules)
COLO-R17 is a benchtop colorimeter spectrophotometer with D/8 illumination geometry and a large Φ50 mm test aperture,
designed for color measurement and comparison of non-transparent materials such as powder, masterbatches, granules and paints.
It supports multiple color spaces and ΔE formulas, and displays spectral reflectance curves for practical QC and color management.
Φ50 mm large aperture
Full spectrum LED
7″ IPS touch display
USB + Bluetooth
30,000 samples
COLO.Science — COLOR QC FOR POWDER, MASTERBATCH & GRANULES
Why COLO-R17 is built for non-transparent samples
COLO-R17 uses D/8 illumination geometry with specular component included (SCI) and a large Φ50 mm aperture to support repeatable
bench measurements on powders, masterbatches and granules. Results include common color parameters, ΔE evaluation, and spectral
reflectance curves for consistent quality control and documentation.
It is typically used for incoming inspection, batch-to-batch consistency checks, supplier comparisons, and production QC in plastics,
coatings/paints, food, pharma and related materials where stable color data is required.
Highlighted capabilities
- Large Φ50 mm aperture for powder & granule measurement.
- 100 mm integrating sphere design (application-oriented, stable measurement geometry).
- Spectral reflectance curve display for deeper QC insight.
- Fast operation via a large 7-inch touch screen.
- PC software + mobile app for data export, sharing and reporting.
Where it fits best
- Masterbatch / plastic granules color control.
- Powder and pigment comparisons (reference vs sample).
- Incoming inspection and supplier verification.
- Production QC with reporting and traceability.
HIGHLIGHTS (INSTRUMENT + WORKFLOW)
What users notice first
Practical note: for powders and granules, use a consistent sample presentation technique and keep the measurement surface uniform to improve repeatability.
COLO.Science & implementation support
We help you define measurement conditions, reference standards, tolerances and a practical pass/warn/fail routine aligned with your materials and QC workflow.
If your samples require a specific handling method (powder box, presentation accessories) we can propose a suitable configuration.
