Lovibond™ Petroleum Oils 3000 Comparator

Single scale, three-field instrument for visual color grading by direct comparison between the sample and Lovibond glass color standards housed in a pair of discs. The advantage of a three-section field of view is that the sample and two consecutive glasses on the color scale are viewed simultaneously, making it easier to achieve the optimum color match. For rapid color grading within predetermined color limits, the glass standards can be set to the two limiting colors so that it is easy to check that the sample is within tolerance.
