Description

The CHNSpec DS-173 Colorimeter is designed for colour measurement and colour difference quality control across a wide range of materials. It supports routine inspections, sample comparisons, and colour consistency checks in industries such as plastics, coatings, printing, textiles, and paper.

Combining spectral measurement with a switchable UV light source, the DS-173 measures both regular and fluorescent materials. Its colour touchscreen, standalone colour matching functions, and Windows software support make it suitable for on-site inspections and colour data management.

Key Features

  • Spectral colour measurement:
    Measures spectral reflectance and provides multiple colour data formats for sample evaluation and colour difference analysis.
  • Switchable UV illumination:
    Compare measurements with UV illumination enabled or disabled to assess how fluorescent components affect colour, whiteness, and yellowness.
  • Multiple measurement indices:
    Evaluate colour difference, whiteness, yellowness, blackness, colour density, opacity, and colour strength using one instrument.
  • Flexible viewing conditions:
    Supports multiple standard illuminants and observer settings to evaluate samples under different measurement conditions.
  • Standalone colour matching:
    Compare samples against stored references and create custom colour card libraries directly on the instrument.
  • Software-supported data management:
    Connect to Windows software to organize measurement records and support further colour analysis.

Evaluate Regular and Fluorescent Materials

Materials containing fluorescent whitening agents or fluorescent pigments can respond differently under UV illumination. The DS-173 allows users to compare results with its UV source switched on and off, helping identify the contribution of fluorescence to the measured appearance.

This function supports more informed colour assessments for materials such as paper, textiles, and plastics, where fluorescent additives may influence colour consistency.

Support Your Colour Quality Control

Use the DS-173 to compare production samples with reference colours, check differences between batches, and maintain colour measurement records. Single and average measurement modes provide flexibility when assessing samples, while stored colour references help streamline repeated inspections.

Applications

  • Plastics and moulded components
  • Paints, coatings, and inks
  • Printing and paper products
  • Textiles and leather
  • Ceramics and stone
  • Food colour quality control
