(Discontinued) CR-331c Chroma Meter

The CR series Chroma Meters from Konica Minolta are crafted to be portable, lightweight, compact tristimulus colorimeters for measuring color differences and reflected color in a vast range of industrial fields. There are five models in the CR series that are perfect for an array of applications. All of the CR models provide excellent inter-instrument agreement allowing for color control of multiple units within a single company or between two or more companies.

The CR-331C Chroma Meter features a 45° circumferential illumination/0° viewing geometry and a Ø25mm measuring area that is perfect for glossy surfaces with directional characteristics.

Illuminating/viewing system

The measuring head of the CR-331c uses 45° circumferential illumination/0° viewing angle geometry. Light from the pulsed xenon arc lamp is projected onto the specimen surface at an angle of 45° by 16 optical fibers arranged in a circle around the measurement axis. This provides uniform illumination over the ø25mm measuring area, and eliminates the problem of variation in measurement values according to the orientation of the specimen in relation to the optical fibers. Only the light reflected perpendicular to the specimen surface is collected by the optical-fiber cable for color analysis

  • Shiny metal specimens should not be measured with this instrument since most of the color of the metal (gold, aluminum, etc.) will be reflected at the specular angle (45°)

Data Processor(DP-301) Features

Full portability for On-the-Go Color Control

Each CR-300 series Chroma Meter consists of a lightweight, handheld measuring head and a compact, battery-operable data-processor. The whole system is fully portable and can be used wherever the measurement subject is, indoors or outdoors, for on-the-spot color control.

Variety of Data-Processing Functions

The data processor of the CR-300 series Chroma Meters is an all-in-one unit with an LCD display, thermal printer, and RS-232C, remote-control, and ΔE*ab alarm terminals.

Data can be displayed, printed out, or output in a variety of color systems.

To provide the highest measurement accuracy, the data processor is equipped with a multicalibration function, which utilizes all calibration data in memory (calibration data can be stored in up to 20 memory channels) in calculating the measurement data. Users can also select a single calibration memory channel if desired.

Other features of the data processor include: Memory space for 300 sets of measurement data; 20 memory channels for target data for color difference measurements; statistical calculations; an interval timer for automatic, timer-controlled measurements; and a ΔE*ab alarm function.
