Transmission SpectrocoloriMeter

The transmission spectrophotometer illuminates transparent samples with a light source, analyzes the transmitted spectrum through a spectroscopic system, and calculates color parameters. It is used for color measurement and quality control of transparent materials such as liquids and films, monitoring color consistency in industries like beverages and coatings.
Selection
When selecting, consider matching the sample's light transmittance characteristics with the instrument's measurement range, ensure the instrument's protection level meets the working environment requirements, and verify that the measurement accuracy satisfies the process tolerance. Compare the light source stability and sensor resolution across different brands, and choose a model that is easy to operate based on the daily testing volume.

Colorimeter controls batch color difference in plastic and rubber films.
This article primarily discusses how to use a colorimeter to control color differences in the production of plastic and rubber films. It explains the working principle of the colorimeter, which involves converting colors into numerical values represented by L, a, and b values, and then calculating the color difference.
Colorimeter evaluates the change in yellowing index of transparent resin.
This article introduces how to use a colorimeter to measure the yellowing index changes in transparent resin. Transparent resin can turn yellow over time or due to environmental influences, and the yellowing index can quantify the degree of color change.
Application of Colorimeters in Color Management for Packaging and Printing
This article mainly discusses the application of colorimeters in color management for packaging and printing. A colorimeter is an instrument used to measure color, capable of converting colors into numerical values, such as representing them with L*a*b* values.
Multi-angle colorimeter detects color changes in pearlescent coatings.
Pearlescent coatings contain special flake pigments that produce color effects that vary with the viewing angle, known as "goniochromism." Traditional single-angle measurements struggle to accurately capture this characteristic.
Application of Colorimeters in Controlling Color Differences in Paint Batches
This article introduces the role of colorimeters in controlling color consistency in paint production. Since human judgment of color is easily influenced by lighting and subjective factors, colorimeters quantify color differences in the CIELAB color space by measuring spectral data, providing an objective basis for production.
Application of Colorimeter and Color Matching Box in Pigment Color Inspection
A colorimeter and a light booth are two primary tools in pigment color inspection. The colorimeter measures color through photoelectric principles, while the light booth provides a standardized light source environment for visual evaluation of color effects, metamerism, and other phenomena.
