Professional color measurement
US$5,995.00
High-precision portable UV grating spectrophotometer with d/8 geometry, SCI/SCE, UV-included and UV-excluded measurement, switchable 8 mm and 4 mm apertures, camera-assisted positioning and USB/Bluetooth data transfer.
The SD-700 is a high-precision portable grating spectrophotometer designed for professional color measurement, color matching and quality control. Its d/8 optical system supports both specular-component-included (SCI) and specular-component-excluded (SCE) measurement, helping teams evaluate intrinsic color as well as the influence of surface appearance.
Combined LED and UV illumination supports measurement with UV included or excluded. This makes the instrument suitable for conventional color work and for samples whose appearance is affected by fluorescence or optical brighteners. Switchable 8 mm and 4 mm measurement apertures, camera-assisted positioning, onboard storage and USB/Bluetooth communication support dependable use in laboratories, production environments and the field.
Some materials change appearance under UV energy because they contain fluorescent whitening agents, optical brighteners or UV-responsive colorants. The SD-700 lets users assess those samples with UV included or excluded, supporting more meaningful comparison of samples, standards and production output where this behaviour matters.
The SD-700 supports incoming-material checks, color matching, tolerance setting, finished-product verification and production quality control. Typical applications include plastics and polymers, paints and coatings, printing inks, textiles and garments, printing and dyeing, paper and printed materials, automotive components and finishes, electronics, cosmetics, food and packaging, medical-related manufacturing, and research or education laboratories.
