Petroleum Oils Comparator (AF650) – 345030
ASTM Oils Scale, 3-Field Visual Measurement
- Compact, Visual Measurement System for Single Scale Measurements
- Self-Contained, Includes Everything Needed to Measure the Scale
- Easy-To-Use, Fast & Accurate
- 3-Field Viewing for Optimum Accuracy
A 3-field instrument for visually determining the color of petroleum oils & waxes samples according to the ASTM Color scale by direct comparison with colored glass filters.
Applications
Petroleum Oils and Waxes
Methods: ASTM D1500, ASTM D6045, ISO 2049
- Accurate Determination of the ASTM Oils Scale
The AF 650 incorporates 16 glass standards which make up the scale in a pair of discs - Fast Determination of Color Value
You can directly compare the sample with the color values for quick results. - Easy to Achieve Optimum Color Accuracy
The advantage of a 3-section field of view is that the sample and two consecutive glasses on the color scale are viewed simultaneously, making it easier and quicker for you to achieve the ideal color match. - Facilitates Tolerance Level Setting
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. - Guaranteed Constant Lighting Conditions
In the instruments, the tungsten halogen light source is color corrected to CIE standard illuminant C*, which guarantees constant lighting conditions for color grading. - Compliance to Standards
Each Comparator 3000 is supplied with the correct cells for the appropriate path length determined by the standard.* In the EBC version, the C filter is replaced by the B filter as required by the standards.
