Summary

YT-0168 Petroleum ProductsColorimeterApplicable to pressSH/T0168-92 "Determination of Color of Petroleum Products" determines the color of various lubricating oils and other petroleum products. The measurement method involves injecting the petroleum product sample to be measured into a colorimetric tube and comparing it with a standard color chart to determine its chromaticity color number.

Product features:

YT-0168petroleum productschromaThe measuring instrument consists of a standard color plate, an observation optical lens, a light source, and a colorimetric tube. Used for light sourceA 220V, 100W, 2750 ± 50K internal frosted milk shell bulb is used as the standard light source. The light from the light source is filtered through a milky white glass plate and a daylight filter 33 glass plate, and the spectral characteristics of the standard light obtained are similar to this light. The standard light passes through a flat mirror and prism to form two parallel beams, which are of identical size and shape, and can be uniformly irradiated onto the sample of the colorimetric tube on the color glass plate of the standard color disc at the same time.

On the standard color palette, there are26 Φ 14 light holes, of which 25 are sequentially equipped with standard color glass sheets of 1-25 color codes. The 26th hole is blank, and the color dial is rotated by the handwheel on the right side of the instrument for selecting the correct equivalent color during colorimetric testing. The standard color glass color on the color palette should be calibrated using a colorimetric solution as the calibration standard color.

The colorimetric tube has an inner diameter of ΦA colorless flat bottomed glass tube measuring 32 millimeters and 120-130 millimeters in height. The colorimetric tube is placed in the small cover position on the top of the instrument.

The observation eyepiece consists of a concave mirror and a dividing grid. Two semi-circular colors can be seen simultaneously in the eyepiece, with the color on the left being the sample color. The one on the right is the standard color, and the optical eyepiece has the ability to adjust light and focus, making it easy to use.
