AF509C for Marine Diesel Fuel Type F76 – 415090
Kit for Visual Color Grading of Type F76 Marine Diesel Fuels according to ASTM Color
- Two-Field Vision for Accurate Results
- Ability to Guarantee Constant Lighting Conditions
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. You only need to rotate the disc to get the closest result to the scale.
Applications
Petroleum Oils and Waxes
Methods: ASTM D1500, ASTM D1645, ISO 2049
- Quick, On-site Color Measurement
This special kit enables you to quickly measure the color of type F76 marine diesel fuels according to a limited range of the ASTM Color Scale. It is designed to ensure that the correct fuel is used in motor vessels running with type F76 diesel, thereby avoiding errors in fuel use that can result in expensive corrective maintenance. The test is based on a direct color match between the sample and a test disc containing ASTM Color standards, enabling you to accept or reject the diesel fuel in a matter of minutes. - Easy Determination
The Lovibond® AF 509/C includes a test disc containing a limited range of ASTM Color standards (1 – 5 units as opposed to the full range of 0.5 – 8 units). This is sufficient for this purpose since type F76 fuel has a target color of 3.5 ASTM Color and reduces the options for you to choose from. - 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 that 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 be 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.
