Micro-Aperture ColoriMeter

The small aperture colorimeter calculates the color difference from standard samples by measuring the tristimulus values of light reflected from an object's surface. It is used to detect color differences on curved surfaces and small-area samples, and to monitor color consistency in the production of printing inks, plastic parts, and other applications.
Selection
When selecting, consider matching the measurement aperture to the sample size; for curved surface measurements, choose models with surface compensation functionality. Pay attention to repeatability indicators and inter-instrument variability to ensure compatibility with data from existing equipment. Select models that include specular reflection or ultraviolet light based on the material characteristics.

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.
Key steps for measuring the efflux time of varnish using a viscosity cup method
This article introduces the method for measuring the outflow time of varnish using a viscosity cup. The principle is based on Poiseuille's law, where viscosity is estimated by recording the time it takes for the liquid to completely flow out from the small hole at the bottom of the cup—longer times typically indicate higher viscosity.
