A series of 3-field instruments designed for visual color grading by direct comparison between the sample and colored glass standards. The sample and two adjacent glasses on the color scale are viewed simultaneously, making it easier to achieve the optimum color match. The tungsten halogen light source is color corrected to CIE Standard Illuminant C (B for the EBC Comparator 3000) and guarantees constant lighting conditions for color grading. Versions of the Comparator 3000 are available for the following scales, each supplied with the appropriate range of color standards and sample containers. 110 Volt.
