COLO.Science — PORTABLE COLOR QC INSTRUMENT
Why COTS7700 is a practical choice for color measurement
COTS7700 is a portable spectro-colorimeter designed for reflectance measurement and day-to-day color control. It supports multiple color spaces and illuminants, provides fast measurements, and displays results clearly on a capacitive touchscreen.
Typical applications include incoming material control, batch-to-batch consistency checks, and production QC in paints/coatings, plastics, printing, textiles, and general manufacturing where repeatable color data is needed.
Key features (short)
- Diffuse / 0° optical geometry with SCI mode.
- Combined LED light source with pulsed xenon lamp.
- Fast measurement: ~1 second (typ.).
- Large data capacity: 1,000 standards + 30,000 samples (typ.).
- Connectivity: USB, RS-232C, Bluetooth 4.2.
Where it fits best
- Routine production QC (pass/warn/fail).
- Incoming inspection and supplier comparisons.
- Color difference tracking (ΔE) and reporting.
- Lab verification and documentation workflows.
HIGHLIGHTS (INSTRUMENT + SOFTWARE)
What users notice first
Tip: for best repeatability, keep measurement pressure/position consistent and re-check calibration on schedule (white/black calibration cavity per kit).
COLO.Science & implementation support
We help you define measurement conditions (illumination/observer, tolerances, pass/warn/fail thresholds) and set up a practical QC routine aligned with your materials and production flow.
If your application requires geometry, apertures, or accessories not listed, we can propose a matching configuration.
