Professional Colour and Spectral Measurement
The CHNSpec DS-173 is a portable spectrophotometer designed for accurate colour measurement, spectral reflectance analysis and colour difference quality control. Featuring D/8 SCI measurement geometry and a high-performance spectral sensor, it delivers repeatable measurements across a wide range of industrial materials.
With a spectral range of 400–700 nm and 10 nm wavelength intervals, the DS-173 supports detailed colour evaluation for manufacturing inspection, product development and quality assurance.
Switchable UV Measurement for Fluorescent Materials
The DS-173 features an independently switchable UV light source, allowing users to compare measurement results with UV illumination enabled or disabled.
This capability is particularly useful for evaluating materials containing fluorescent whitening agents or fluorescent pigments, including paper, textiles, plastics and coatings. Users can assess the influence of fluorescent components on colour, whiteness and yellowness.
Comprehensive Colour Analysis and Matching
The instrument supports multiple colour spaces, colour difference formulas and industry-standard measurement indices, including CIE-Lab, CIE-LCh, ΔE*00, whiteness, yellowness, blackness, colour density and opacity.
Built-in colour matching capabilities, custom colour card libraries and support for up to 10,000 stored measurements help streamline colour comparison and quality control workflows.
Convenient Touchscreen Operation and Data Management
A 3.5-inch full-colour touchscreen provides straightforward access to measurement results and instrument settings. The 11 mm aperture is particularly useful for measuring materials with surface texture or local colour variation.
With approximately 1-second measurement time, USB connectivity and dedicated Windows software, the DS-173 is suitable for both on-site inspection and professional colour data management.
