Product information

  • Self-Contained Kit to Determine Quinizarin Market
    The AF 626 contains everything you need to determine the correct amount of Quinizarin Marker is present in diesel fuel.
  • Fast, Economical & Portable Visual Matching
    The Comparator 2000+ is a flexible, modular system for Visual Color Grading. Using a suitable comparator instrument and glass disc, you can quickly visually match the sample directly against the calibrated, color stable glass standards.
  • Two-Field Vision for Accurate Results
    Lovibond® comparator instruments include an integrated prism which causes the sample and comparison fields to overlap, allowing enhanced color discrimination and matching. The prism is ultrasonically sealed to prevent contamination of the optics. Each individually graded glass standard represents a discrete step on the measurement range (as opposed to a continuous graduation), aiding color discrimination and allowing great accuracy of results.
  • Ability to Guarantee Constant Lighting Conditions
    An optional item for the Comparator 2000+ is the Daylight 2000 Lighting Unit. This is a standardized light source which guarantees you a constant lighting condition for accurate color grading. This is particularly useful when the sample is very pale in color. By using a Lovibond® lighting unit, you can confident of uniform lighting conditions for color matching, 24 hours a day and irrespective of ambient lighting.
  • Extended Shelf Life
    The unique feature of Lovibond® test discs is that they incorporate colored glass standards that are color stable and not affected by UV light or extreme environmental conditions.
    Please note, we cannot guarantee compatibility of discontinued Lovibond® Comparator 1000 disks with the Lovibond® 2000+ Comparator.
