Konica Minolta CR-400 Chroma Meter

Konica Minolta CR-400 Colorimeter

The Konica Minolta CR-400 colorimeter, an upgraded product from the CR-300, is fully backward-compatible with its predecessor. This enables a seamless transition from the CR-300 to the CR-400, allowing legacy data to be fully utilized on the new instrument.

With the capacity to store up to 1,000 measurement records within its internal memory, and expandable up to 2,000 records via connection to the data processor, the Konica Minolta CR-400 colorimeter offers high operational flexibility. The instrument is not only highly portable and easy to operate but is also capable of executing measurements across a wide range of products and surface types in versatile applications.

The data processor of the instrument, which is compact and can be operated by either batteries or an AC adapter, supports instantaneous printing of results, making quality labeling highly convenient. The CR-400 also integrates a user index functionality, allowing operators to customize colorimetric formulas and evaluation methods. This is critical when deploying industry-specific proprietary formulas rather than relying solely on standard color spaces and evaluation systems ($L^*a^*b^*$).

Applications of Konica Minolta CR-400 Colorimeter

• Widely utilized across sectors such as building materials, food industries, and chemical manufacturing.
• Ideally suited for specimens with smooth surface textures and minimal color variation, featuring a standard Ø8 mm measurement aperture.
• Capable of flexibly measuring powders, granules, liquids, and pastes when paired with optional specialized accessories.
