The ASTM D 1500 color scale is applicable to a wide range of petroleum products, such as lubricating oils, heating oils, diesel fuel oils and petroleum waxes. The ASTM D 1500 color scale is the principal quality measurement used for the purchase and sale of partially refined oils.
As an oil is refined, there exists a correlation between the color of the distillate and the degree of refinement. During the refining process, crude oil is transformed into a range of products with distinct colors ranging from the dark red-black of crude through to the pale yellow hue of the lighter fractions. The distinct petroleum colors can be accurately measured and the refinement process controlled using the ASTM D 1500 color scale.
The ASTM D 1500 color scale is also used for product and interface detection, and for product contamination monitoring.
The Kemtrak DCP007-VIS Photometer is an easy to operate industrial fiber optic photometer designed to accurately measure the concentration and color of process samples. Measurements are real time and in-line.
The Kemtrak DCP007 uses a long life high performance LED light source with robust industrial grade fiber optics to provide drift and noise-free measurement with very high precision.
A proprietary dual wavelength four channel measurement technique and advanced digital electronics design allows deep absorbance measurement to 5 AU. A range of shorter optical pathlengths allow for deeper absorbance measurements. Automatic compensation for sample turbidity and/or fouling of the optical windows ensures trouble free operation.
Maintenance free measurement cells with sapphire windows have no electronics or moving parts making the unit suitable for hazardous area use.
