The Color Chart reader is an instrument used to measure color values, mainly used in medicine, textile, food, cosmetics, paint, printing and other industries. The following is a detailed introduction to the selection points and precautions of the Color Chart reader.
select points
Measuring range: Choose a suitable instrument according to the required measuring range. Typically, color meters measure lightness values from 0-100, red, green, and blue values from -100 to 100, and hue and saturation values.
Accuracy: Accuracy is an important factor to be considered when selecting a Color Chart reader, and an instrument with appropriate accuracy should be selected according to actual needs.
Repeatability: Repeatability refers to the consistency of multiple measurement results for the same sample under the same measurement conditions. Good repeatability can improve the reliability of measurement results.
Other functions: Some high-end Color Chart readers also have functions such as automatic calibration and automatic color recognition, which can improve the efficiency and accuracy of measurement.
Precautions
When using the instrument, avoid direct sunlight, high temperature, humidity and other environments that affect the measurement results.
Before the measurement, the surface of the measuring object should be guaranteed to be clean and free of pollution, and try to avoid touching the measuring object with hands.
When measuring, the measurement angle and light source should be selected according to actual needs, and the consistency of measurement conditions should be maintained.
The instrument should be cleaned in time after use and stored in a dry, ventilated and dust-proof environment.
