Since part of the light will pass through the light-transmitting materials, the colorimeter is not suitable for color measurement of such kinds of materials; however, when place a pure color material with uniform texture under the light-transmitting material, we can measure the color difference between the standard and the sample.
The repeatability is an important parameter for the accuracy of the colorimeter. Threenh Technology portable colorimeter for color measurements tandard deviation ΔE*ab is within 0.03 (Measurement condition: the average value of 30 measurements on the white board at an interval of 3s after calibration). Each colorimeter can pass the qualified inspection before leaving the factory to ensure it conforms to the standard of China Metrology Institute.
A colorimeter is a scientific instrument used to measure and analyze the color characteristics of objects or materials. It quantifies color by evaluating specific parameters related to human visual perception and standardized color spaces.
