Chroma Meter CR-400
The Konica Minolta Chroma Meter CR-400, the successor to the CR-300, is a versatile colorimeter designed to provide precise measurement of colors of various types of products and surfaces across different applications, specifically catering to samples with smoother surface conditions or minimal color variation. Its high accuracy and reliability ensure a more streamlined and efficient process within your operations and throughout the supply chain, whether quality control and assurance or research and development.
This handheld, portable color measurement instrument features an ⌀8mm measurement aperture and is ideal for color inspections of food, building materials, plastics, and dermatological applications. The Chroma Meter CR-400 excels at quantifying color characteristics and determining color differences. With its pass/fail assessments feature, users can immediately verify if their sample aligns with the predefined standard or target. Furthermore, users can also customize their color evaluation or color calculation formulas to meet their industry-specific or intended application needs.
The Chroma Meter CR-400 can store up to 1,000 measurements internally and 2,000 with the optional data processor attached. Plus, it boasts a user-friendly design with a large LCD screen that presents data and graphs. The Chroma Meter CR-400 is supported by a variety of accessories to accommodate various samples, whether powders, opaque liquids, or pastes. Additionally, optional software like SpectraMagic™ NX2/SpectraMagic™ NX is available to enhance the Chroma Meter CR-400 for thorough color analysis and quality control.
