CM-2500c Spectrophotometer

View our latest version of this instrument, the CM-25cG

Recognized as the industry leader of its kind, the CM-2500c Spectrophotometer is a portable 45/0 instrument built to measure the color of samples with stability and unwavering performance. This instrument’s innovative optical system captures the entirety of a sample’s color at any angle or position, enabling users to precisely evaluate, reproduce, and control the color of materials with uneven, curved, or textured surfaces. Its advanced capabilities help to define color specifications, determine if a sample meets the standard, and maintain consistency in each batch of material more efficiently. This makes the CM-2500c ideal for R&D analysis, quality control inspections, and process control procedures.

The CM-2500c Spectrophotometer is compatible with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis.


  • Eligible ISO 17025 Certification
  • Innovative 45/0 geometry system prevents measurement fluctuations for stable, consistent results; ideal for uneven, textured, or curved surfaces
  • Pass/fail assessments immediately determines if the sample meets the defined standard or target color
  • Data displays measurement results, color differences, spectral graphs, and tolerance data clearly for easy interpretation
  • Portable and lightweight handheld design powered by batteries or AC adapter
  • Simple, straightforward navigation wheel with options easily understood by new users
  • Six language options – English, Spanish, French, German, Italian, and Japanese
  • Integrates with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis
