Platinum-Cobalt/Hazen/APHA Colour Scale, Range 0 - 250 mg
Visual Color Grading of Platinum-Cobalt/Hazen/APHA Color
The Lovibond® AF329 is a special kit for visual color grading using Platinum-Cobalt/Hazen/APHA Color over the range of 0 - 250 mg Pt/l.It is typically used for light yellow liquids such as water, oils, and chemicals. Because the sample colors are relatively unsaturated, the kit employs a long path length Nessleriser comparator to give greater measurement sensitivity and accuracy. The Comparator 2000+ is an easy-to-use, entry-level color measurement system that compares the color of the sample directly against the color of glass in a disc. All you need to do is rotate the disc to get the closest result to the scale.
- Greater Measurement Sensitivity and Accuracy
The Lovibond® AF329 is a special kit for visual color grading using Platinum-Cobalt/Hazen/APHA Color over the range 0 - 250 mg Pt/l. It is typically used for light yellow liquids such as water, oils, and chemicals. The color is determined by visually matching a column of sample in a Nessler cylinder with precalibrated colored glass standards, which are stable colored and not affected by UV light or extreme environmental conditions. Because the sample colors are relatively unsaturated, the kit employs a long path length Nessleriser comparator to give accurate readings.
- 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 that 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 that guarantees you a constant lighting conditions for accurate color grading. This is particularly useful when the sample is very pale in color. By using a Lovibond® lighting unit, you can be confident of uniform lighting conditions for color matching, 24 hours a day and irrespective of ambient lighting.
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.
