Chroma Meter CR-400
Compatible with the CR-300, the handheld CR-400 chroma meter is its improved successor. Upgrading is easy for current CR-300 owners because existing data can be used.
Able to store up to 1,000 measurements internally, or 2,000 when the data processor is connected, the CR-400 chroma meter is also portable and easy-to-use, plus it has the ability to measure different types of products and multiple kinds of surfaces in various applications.
The lightweight, compact data processor can be operated by battery or can be connected by AC adapter, and with its ability to print results on-site, labeling is easy. Featuring a user index function, the CR-400 series allows customers to configure evaluation and color calculation formulas as desired. This feature is extremely useful when customized or industry-specific formulas are used instead of the versatile color system and standard evaluation formula (L*a*b*).
The CR-400 chroma meter’s LCD screen is capable of displaying pass/fail information and color-difference graphs, and can be set in any of six different languages, including English, Spanish, Italian, Japanese, French and German. Type user comments into the results or, by using the data processor, customers can determine channel names. A variety of accessories are available to accommodate various target types such as powders, liquids, and pastes.
The CR-400 chroma meter is compatible with SpectraMagic NX software and is easy-to-use. Multiple views of data results can be viewed and edited. By associating target data of the primary target with two or more secondary targets, sophisticated QC applications are allowed, such as checking for color difference.
Data interpretation is easy. Simply drag-and-drop information into the software then print. Display information on a variety of graphs, or utilize preconfigured templates, and view instrument information at a glance in the available status window. Thanks to maximum compatibility, data compiled with older software can be transferred to the newest updated software so nothing is lost. Export information into Excel if needed, and get additional information on the spot utilizing the Navigation Function and Color Tutorial included with the software.
