Kemtrak Photometer DCP007-VIS
DESCRIPTION
Kemtrak - 'It is a leading manufacturer of fiber optic instrumentation and automation products for process applications.
Conventional-photometers use mercury photometers, which continuously expose samples to a wide range of radiation and heat generated by mercury lamps. This has negative consequences for both the equipment. A more efficient and market proven technology is the Kemtrak DCP007.
The Kemtrak DCP007-VIS flow analyzer is a high-performance fiber optic photometer for measuring concentrations of substances in solutions in real time with high resolution.
The Kemtrak DCP007 UV photometer measures two wavelengths. A primary "absorbing" wavelength is used to measure the observed substance, and a "non-absorbing" reference wavelength is used to compensate for turbidity, air bubbles and/or contamination.
Light sources can easily be replaced on Kemtrak DCP007 photometers and the configuration changed to measure other desired wavelengths. The Kemtrak DCP007-VIS operates in wavelength ranges from 250 to 1050 nm and if a liquid or gas has an optical density in this range, the Kemtrak DCP007-VIS can measure it

Examples of Applications:
ASTM D 156 - Seybolt Scale
The Saybolt color scale has traditionally relied on the comparison of a standard color disk viewed through an adjustable sample volume. This dimensional color scale is subject to bias by erroneous operator decisions. Kemtrak DCP007 technology standardizes and automates the processes used to evaluate Saybolt Scale products.
ASTM D 1500
The ASTM D 1500 color scale is applicable to a wide range of petroleum products, such as lubricating oils, heating oils, diesel fuels and waxes. The ASTM D 1500 color scale is the primary quality measurement used for the purchase, and sale of partially refined oils.
As the oil is refined, there is a correlation between the color of the distillate and the degree of refining. During the refining process, crude oils have evolved into an assortment of products with distinct colors ranging from dark red to black to pale yellow tinged lighter fractions. Distinctively colored petroleum subducts can be accurately measured and defined using the ASTM D color scale.
The ASTM D 1500 color scale is also used for product and interface identification and for product contamination monitoring.
All of these can be determined by Kemtrak DCP007-VIS technology.
