Features

  • The AF325 is ideal for the color grading of lighter liquids according to Platinum-Cobalt/Hazen/APHA Color over the range 10 - 250 mg Pt/l.
  • Visual test kit is ideal for relatively unsaturated liquids due to its extended path length.

  • 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.

  • Includes an integrated prism which causes the sample and comparison fields to overlap, allowing enhanced colour 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.

  • An optional item is the Daylight 2000 Lighting Unit. This is a standardized light source which guarantees you a constant lighting condition for accurate colour grading. This is particularly useful when the sample is very pale in color. By using a lighting unit, you can confident of uniform lighting conditions for color matching, 24 hours a day and irrespective of ambient lighting.

  • The unique feature of test discs is that they incorporate colored glass standards that are color stable and not affected by UV light or extreme environmental conditions
