The CM-700d Spectrophotometer is a handheld, portable measurement instrument designed to evaluate the color and appearance of samples very small to large in size, including objects with flat, shaped, or curved surfaces. This high precision, reliable spectrophotometer allows users to evaluate, reproduce, and control the color of pigments and dyes in a more effective, streamlined process. Its advanced capabilities help establish and meet color quality standards more efficiently, maintain consistency in each batch of material, and communicate color seamlessly internally and throughout the supply chain. This makes the CM-700d ideal for color analysis, formulation, quality control inspections, and process control procedures within research and manufacturing environments.
The CM-700d Spectrophotometer is 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. For dermatological applications, the CM-700d can also be used with CM-SA Skin Analysis software.
