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 NX2 software to record measurements and provide a more comprehensive color analysis, as well as others software to formulate color recipes for various applications.
