3 Overview

3.1 petroleum products color analyzer Petroleum products color analyzer (hereinafter referred to as instruments) are measured for various lubricating oils, kerosene, diesel, petroleum wax Color of Petroleum Products instrument can be divided into automatic instruments and visual equipment. The color of petroleum products are divided into 16 color number, From shallow to deep were 0.5,1.0,1.5,2.0,2.5,3.0,3.5,4.0,4.5,5.0,5.5,6.0, 6.5,7.0,7.5,8.0. Automated instruments mainly by the light source, a beam system, the sample chamber, the detection system components. Meet the 0.0 ~ 8.0 Determination of color. Visual equipment mainly by the light source, the standard color wheel, prism and eyepiece observation and other components, together with colorimetric tube. Measurement Sample injection timing of petroleum products intended color measurement than the inner tube, and then test the sample chamber into the instrument, the instrument light filter After color refraction and reflection respectively through the prism of uniform illumination on the color wheel and colorimetric shade guide tube, by observing the ratio of the eyepiece Swatches compared to determine which color color number. 3.2 Saybolt colorimeter Saybolt colorimeter is measured unstained motor gasoline, aviation gasoline, jet fuel, naphtha, kerosene, white Oil and other refined petroleum products, petroleum wax color instrument. The ratio of color swatches is measured by comparing the color samples of the liquid column Degrees, when the contrast ratio and observation sample swatches through the liquid column, measured the height of the liquid column and three match one swatch closest, Value, this value can be isolated by Saybolt color number. Saybolt color number of provisions -16 (darkest) to 30 (most shallow). Mainly by the standard sample tube, an optical system, a light source, standard color and other components. ......
