CS7030 Portable Spectrophotometer — d/8, SCI and SCE, Ø8 mm aperture
The CS7030 portable spectrophotometer (COLO product code PRO7958) measures colour and colour difference of plastics, paints, inks, textiles and paper with d/8 geometry and simultaneous SCI and SCE. A combined LED light source, an Ø8 mm aperture and a built-in positioning camera make it a handheld instrument for colour quality control in the laboratory and at the production line.

The CS7030 keeps the optics, sensor and camera of the CS7036 and leaves out what many users do not need every day: the UV lamp, the small Ø4 mm aperture and Bluetooth. Results are transferred to the PC software by USB.
Key characteristics
- d/8 geometry, SCI and SCE measured simultaneously
- Combined LED light source, 400–700 nm in 10 nm steps
- Aperture Ø8 mm (Ø10 mm illumination)
- Repeatability ΔE*ab ≤ 0.06, inter-instrument agreement ΔE*ab ≤ 0.3
- Built-in camera for positioning, 3.5″ touch screen
- USB, 1 000 standards and 20 000 samples
Suitable for
- Plastic parts, plaques, masterbatch and granules (with the powder test box)
- Paints, coatings, inks and printed material
- Textiles, leather and paper
- Colour quality control with CIE Lab (D65/10°) and ΔE pass/fail at the line or at goods receipt
Why this instrument
Most colour checks in production compare a sample with a standard under D65 and decide pass or fail. For this the CS7030 provides full-spectrum data and SCI/SCE measurement, so glossy and textured samples can be judged as the eye sees them (SCE) or independent of gloss (SCI) — without paying for UV and a second aperture where they are not needed.

Software and data
The PC software (free download) stores standards with their tolerances, shows the spectrum and the colour difference, follows trends and exports results for reports. Standards can also be created and measured directly on the instrument.
Data are transferred by USB.
Standard delivery

Knowledge base
New to colour measurement? Light sources, metamerism, CIE Lab, ΔE and measuring geometries are explained on COLO.Science, our knowledge base.
Selection guide
- Fluorescent or optically brightened samples, small parts: CS7036 — UV lamp and a second Ø4 mm aperture, Bluetooth.
- Full spectrum and SCI/SCE without UV: CS7030 — same optics and camera, Ø8 mm aperture, USB.
- Lab and ΔE with PC software, budget first: CS7020.
- Pass/fail on the spot, no PC: CS7010.
- Transmittance, liquids or haze: a benchtop spectrophotometer is needed — see the CS60 series.
