Description

The DS-700-A / D / E series are professional-grade portable spectrophotometers engineered for precise color measurement, quality control, and color matching in industries such as coatings, plastics, textiles, printing, and paints. These handheld instruments employ grating spectroscopy technology with a full-wavelength balanced LED (and UV in some versions) light source covering the visible spectrum (typically 400–700 nm).

Key features across the series include:

• Portable and ergonomic design for field or laboratory use with built-in rechargeable battery, USB/Bluetooth connectivity, and a color LCD screen.

• Automatic calibration with a reference white tile, ensuring consistent measurement accuracy without frequent manual adjustments.

• Spectral measurement of reflectance and calculation of standard color values such as CIE-Lab, CIE-XYZ and color difference metrics (ΔE, whiteness, yellowness, etc.).

• Multiple measurement apertures for different sample sizes (varies by model).

• Data storage and software support for smartphones, tablets, and PCs (Android, iOS, Windows), enabling easy data management and integration into quality workflows.

Model differences:

• DS-700A: Typically offers a set of measurement apertures and solid repeatability suitable for general surface color measurement.

• DS-700D: Often includes more apertures and slightly tighter repeatability/inter-instrument agreement for more demanding color control tasks.

• DS-700E: Similar to the D model but may offer variations in aperture set or optimized operability for specific use cases.

These units are widely used where accurate, portable color analysis is needed — for example, in production quality control, color matching labs, material inspection, or surface evaluation tasks.
