Technical features: 1. According to SH / T0168-92 "petroleum product color determination" determination of various lubricants and other petroleum products color. 2. Light source with 220V, 100W, the temperature of 2750 ± 50K within the frosted shell light bulb as the standard light source, the light source through the milky white glass and daylight filter 33 glass filter color, the standard light spectral characteristics similar to the This light. Standard light through the plane mirror, prism composed of two parallel beams, the size of the shape of the same, can also be uniformly irradiated on the color of the standard color plate on the color of the sample tube. 3. Standard color plate has 26 Φ14 light hole, of which 25 were sequentially fitted with 1-25 color standard color glass, 26 holes for the blank, color plate mounted on the right side of the instrument hand wheel rotation, So as to select the correct color when comparing the color test. The standard color glass color on the color plate should be calibrated as a colorimetric solution for calibration standard color. 4. Colorimetric tube for the diameter Φ32 mm, 120-130 mm high colorless flat glass tube. The color tube is placed in the small cap position at the top of the instrument. 5. Observation of the eyepiece by the concave mirror and the separation gate, in the eyepiece can also see two semi-round color, the left side of the sample color. The right side of the standard color for the color, optical eyepiece with light adjustment and focusing ability, easy to use. Precautions for use: 1. Optical eyepiece system, has been adjusted and light adjustment is correct, should not be used when the need to adjust should also be carefully carried out. 2. When the color tube with oil sample is placed in the instrument, the outer surface of the test tube and the bottom must be cleaned. 3. Standard color glass plate every six months, must be specified by SH / T0168 calibration colorimetric liquid for a time, if found color and color color of the color difference between the color difference of a color number, should replace the new The color plate or send the factory to re-calibration.
