Lovibond® 3000 Comparator Series
 A series of single scale, 3-field instruments designed for visual colour grading by direct comparison between the sample and Lovibond® coloured glass filters housed in test discs. The sample and two consecutive glasses on the colour scale are viewed simultaneously, making it easier to achieve the optimum colour match. For rapid colour grading within predetermined colour limits, the glass standards can be set to the two limiting colours so that it is easy to check that the sample is within tolerance. The tungsten halogen light source is colour corrected to CIE Standard Illuminant C (CIE Standard Illuminant B for the  EBC instrument), giving constant lighting conditions for colour grading, regardless of ambient lighting.
A prism brings the three fields together to aid colour grading
