Description
The famous Chroma Meters series – more powerful and versatile then ever
The Konica Minolta Chroma Meters CR-400 series continue the heritage of the first portable colorimeters introduced in the Eighties.
The CR-400, with its 8 mm measuring area is suitable for measuring reflected colour and colour difference in a wide range of industrial fields. It is able to meet the needs of various applications, from all sorts of ingredients, foods, raw materials and finished products to pharmaceuticals and dermatological applications.
If samples are structured or uneven in surface, such as granulates, fabrics, wood, stones, bricks, then the CR-410 is the right choice. Its unique very large aperture of 50 mm is perfectly suited for such samples and thus avoids averaging of several measurements.
Features
The 400 series offer enhanced usability and functionality such as the re-designed Data Processor, featuring a large back light display for numerical or graphic display of measurement data and a built-in thermal high speed printer. The data memory now can store up to 100 target colours and up to 2000 measurements. Several new colour spaces and Pass/Fail formulas as well as indices for whiteness and yellowness enhance the usage into various fields of applications. The new “user indices” function allows the input of up to six different user or application specific equations using XYZ, Yxy or CIELAB values. Furthermore, the communication languages can be set for English, German, French, Italian, Spanish and Japanese.
For even more user flexibility the measuring head, equipped with Display, function keys and power supply, can now be used as “stand alone” or directly interfaced to the PC to run with the optional QC software SpectraMagic NX.
With all these features, the unsurpassed ease of use and the legendary ruggedness, the fourth generation of Chroma Meters is bound to continue its success throughout the world of modern colour control.
Main Features
- The measuring head can be disconnected from the Data Processor to perform measurements independently. In addition, it is also possible to link the measuring head directly to a PC, and optional software (sold separately) can then be used to allow the PC to carry out data processing in place of the Data Processor.
- Featuring a user index function for the free setting of evaluation and color-calculation
- Several application specific accessories facilitate the measurement of powder, liquid, paste, and many other types of samples.
- Compact Data Processor with integrated thermal printer
- The CR-400 series feature the same illumination/viewing optical system as the previous generation and thus data compatibility is assured.
