CM-5 Spectrophotometer

An advanced all-in-one system, the CM-5 Spectrophotometer is a bench-top measurement instrument designed to evaluate the color and appearance of opaque, transparent, and translucent samples. Its high precision and advanced capabilities allow users to effectively analyze, formulate, and control the color and appearance of solids, liquids, pastes, powders, pills, and granules in a more comprehensive, streamlined process. This makes the CM-5 ideal for color analysis within R&D and laboratory environments.

Used as a standalone instrument, the CM-5 is also compatible with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis, as well as Colibri software to formulate color recipes for various applications.

Features

  • Eligible ISO 17025 Certification
  • Includes aperture sizes, 3mm, 8mm, and 30mm, to evaluate the color and appearance of samples very small to large in size
  • Equipped with a top-port area for measuring opaque samples, as well as a transmittance chamber for measuring transparent and translucent samples
  • Pass/fail assessments immediately determines if the sample meets the defined standard or target color
  • Instrument is calibrated automatically with each start up to maintain its high accuracy and performance
  • Large color LCD screen displays data and graphs clearly, including color values, spectral graphs, and color difference graphs, for interpretation of measurement results
  • Provides an Operation Wizard to guide users through instrument set up and measurement use
  • Individual instrument settings and measurement data can be stored to eliminate confusion between multiple users
  • Various industry-specific indices are stored in the instrument, including Gardner, Hazen/APHA, Iodine Color Number, US and European Pharmacopoeia, to meet application needs quickly and more effectively
  • 8 language options includes English, Spanish, German, Italian, French, Portuguese, Japanese, and simplified Chinese
  • Stores measurement results and displays data numerically and in graph charts, eliminating the need for a computer; can be integrated with SpectraMagic NX software to provide a more comprehensive color analysis, as well as Colibri software to formulate color recipes for various applications
