Overview

EOPTIS offers CLM-194 handheld digital tristimulus colorimeter: a compact device for colorimetric detection with a reliability higher than human eye and at a competitive price.

Colour measurements can be performed on the surface of a wide range of matte and glossy materials, thanks to a (45°c:0°) measurement geometry and the very uniform illumination provided by integrated LEDs.

Long-term stability reduces the need of calibration by the user. The device is powered and interfaced through a USB port using a standard PC or laptop with Microsoft Windows operating system.

After having performed the measurement of the sample of interest, CLM-19X Interface application software allows you to:

  • Evaluate the colour difference from a reference patch, to determine whether a sample is within a user-defined acceptance limit
  • Classify samples among a set of selected colours, in order to group them in classes with homogeneous colour and improve uniformity
  • Find the best match of the sample, looking up a colour database to reproduce the measured colour.

The colour database is encoded in software, avoiding the use of bulky physical sample libraries. Standard colour sets like RAL or Pantone are already included while custom or application-specific colour databases can be added by the user or with EOPTIS' support on request.

Results can be exported to .PDF and .XML format for off-line analysis.

Benefits

  • Quick quality control of raw materials
  • Simplified operation to reduce the human error
  • Objective analysis of semi-finished products and finished products
  • Analysis on heterogeneous materials and surfaces

Technical specifications can be found in CLM-194 brochure.
