View our latest version of this instrument, the CR-410.

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-310 Chroma Meter offers ø50mm measuring area and wide-area illumination/0° viewing geometry for measurements of textured surfaces.

Illuminating/viewing system

The normal head of the CR-310 averages the measurement over a relatively large area. This is especially useful when measuring textured samples, such as carpet or cloth, which might result in measurement errors if a smaller specimen area were used. A pulsed xenon arc(PXA) lamp inside a mixing chamber provides diffuse, uniform lighting over the 50mm diameter area. Only the light reflected perpendicular to the specimen surface is collected by the optical-fiber cable for color-analysis.

  • Since measurements made with this system are greatly influenced by specular reflection, this system should not be used for measuring glossy surfaces.

Color-Control Applications

Textile/dyeing industry

Dyed cloth or fibers; rugs, carpets, drapes, etc.


Color analysis of soil.

Food industry

Processed foods; determining maturity level of raw products.

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.
