(Discontinued) CR-331 Chroma Meter

Konica Minolta CR series Chroma Meters are compact, lightweight, portable tristimulus colorimeters for measuring reflected color and color difference in a wide range of industrial fields. Five different CR-300 series models are available to meet the needs of various applications. All CR-300 series models offer improved inter-instrument agreement to allow multiple units to be used for color control both within a company and between companies.

The CR-331 Chroma Meter offers ø25mm measuring area and 45° bi-directional illumination/0° viewing geometry for accurate measurements of glossy surfaces.

Illuminating/viewing system

The measuring head of the CR-331 enables accurate measurements without the effect of specular reflection. In addition, the reading is averaged over a relatively wide ø25mm area to provide a more uniform response. Light from a pulsed xenon arc (PXA) lamp is projected onto the specimen surface from opposite sides at an angle of 45°. Only the light reflected perpendicular to the specimen surface is collected by an 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°)

Color-Control Applications

Paint Industry

Large surfaces during production.

Textile industry

Silk, metallic-fiber textiles, metal-coated textiles, etc.

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.
