DS-400/ DS-420/ DS-410 spectrophotometer

DS-400/ DS-420/ DS-410 spectrophotometer

1、 Core technology

(1) Dual optical path design improves repeatability accuracy dE * ab ≤ 0.03

The dual optical path design monitors the energy fluctuations of the light source while measuring the sample signal, reduces interference during measurement, achieves higher measurement stability, and improves the instrument’s measurement repeatability index to dE * ab ≤ 0.03. Ensured instrument measurement speed, accuracy, and stability. The relevant technology is protected by Chinese invention patents and American invention patents.

1) More than 30 measurement parameters

• ·RGB, laboratory, spectral reflectance, LCh, Hunter Laboratory, CIE Luv, XYZ, Yxy
• ·Color difference（ Δ E * ab Δ E * cmc Δ E * 44 Δ E * 100)
• ·Whiteness (ASTM E313-00, ASTM E313-73, CIE/ISO, AATCC, Hunter, Taube Berger Stensby)
• ·Yellowness (ASTM D1925, ASTM E313-00, ASTM E313-73)
• ·Blackness (My, dM), color fastness to staining, color fastness to changing, coloring (ASTM E313-00)
• ·Color density CMYK (A, T, E, M), metamerism index Milm, Munsell, covering power, power (dye strength, coloring power)

The DS-400 series offers 10 measurement calibers

• For the convenience of users to measure samples of different sizes, the DS-400 series spectrophotometer supports 10 different apertures for customers to use: stable type: Φ 11mm, Φ 10mm, Φ 6mm, Φ 5mm, Φ 3mm
• Flexible type: ▽ 11mm, ▽ 10mm, ▽ 6mm, ▽ 5mm, ▽ 3mm, can be flexibly applied to various sample testing areas.
