CS7708 Handheld Spectrophotometer — d/8, SCI and SCE, LED and UV, three apertures

The CS7708 handheld spectrophotometer (COLO product code PRO7952) measures colour and colour difference of plastics, paints, inks, textiles, leather and printed material, from large panels down to very small areas. d/8 geometry with simultaneous SCI and SCE, a full-spectrum LED with UV light source and three apertures — Ø8 mm, Ø4 mm and a 1 × 3 mm slot — are combined in a pistol-grip instrument with camera positioning.

Overview

The CS7708 is the top model of the handheld CS77 series. The 1 × 3 mm slot aperture reaches fine lines, narrow edges and small printed elements for colour difference checks (with lower accuracy than the round apertures); the Ø8 and Ø4 mm apertures cover the usual samples, and the UV source makes the instrument suitable for fluorescent and optically brightened materials.

Key characteristics

• d/8 geometry, SCI and SCE measured simultaneously
• Full-spectrum LED and UV light source, 400–700 nm
• Three apertures: Ø8 mm, Ø4 mm and 1 × 3 mm slot
• Repeatability ΔE*ab ≤ 0.03, inter-instrument agreement ΔE*ab ≤ 0.15
• Built-in camera for positioning, 3.5″ touch screen
• USB and Bluetooth, 1 000 standards and 30 000 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

When samples range from painted panels to small parts and printed details, one instrument with three apertures avoids a second device. The CS7708 keeps laboratory-level data for all of them: full spectrum, SCI and SCE in one measurement, 18 illuminants on the instrument and the usual whiteness, yellowness, metamerism and colour strength indices.

On the instrument

Exchangeable aperturesFlat and tip apertures Ø8 and Ø4 mm plus a 1 × 3 mm slot, changed in seconds.

Measurement on the partCamera view and cross-hair place the aperture exactly on large, curved or installed parts.

Calibration cavityWhite and black calibration; the cavity also protects the measuring port during storage.

Powder test box (optional)For powders, granules and pastes measured through the window.

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 or Bluetooth.

Standard delivery

• Instrument with white and black calibration cavity
• Apertures Ø8 mm flat, Ø8 mm tip, Ø4 mm flat, Ø4 mm tip and 1 × 3 mm tip
• PC software (download), USB cable, power adapter, user guide
• Protective cover and wrist strap

Optional: micro printer, powder test box. The delivered configuration for a specific order is the one confirmed in the COLO.Science quotation.

Selection guide

• Very small areas, fine lines, small printed elements: CS7708 — adds a 1 × 3 mm slot aperture to Ø8 and Ø4 mm.
• Fluorescent or optically brightened samples, large and small parts: CS7700 — UV light source, Ø8 and Ø4 mm, Bluetooth.
• Non-fluorescent samples of one size range: CS7600 — same optics and camera, one aperture selected with the order, USB.
• Lighter instrument, routine Lab and ΔE checks: the CS70 portable series.
• Transmittance, liquids or haze: a benchtop spectrophotometer is needed — see the CS60 series.
