Colorimeter is a color measurement tool used to provide color measurement and color comparisons. However, many people still stay at a relatively superficial level with regard to the concept of colorimeters and do not understand  what does colorimeter actually do. In fact, the colorimeter can perform color difference contrast, color test and color quality control,etc. And the colorimeter can display the Lab and Lch values of different colors.

1. What is color difference?

To understand the colorimeter, we must start with the basic concept of color difference. Color difference, if it is to be understood literally, is the "difference of color". The difference or distance between two colors is a metric of interest in color science. It allows quantified examination of a notion that formerly could only be described with adjectives. Quantification of these properties is of great importance to those whose work is color-critical. Common definitions make use of the Euclidean distance in a device independent color space.(Quoted from Wikipedia)


2. Colorimeter applications

Now that we know the specific meaning of color difference, we can continue to understand the specific role of the colorimeter. Sometimes, when we get a sample, we need to collect the color of the standard sample. Linshang LS171 colorimeter can measure the color of the standard sample and quickly match 3 close color codes. Then use the collected color as a model to produce other goods. If you only observe with the naked eye, it is actually difficult to distinguish the difference between the sample and the standard sample. Therefore, in this case, the colorimeter can play its role.

In addition, the colorimeter can also be used in the manufacturing process of some industrial products. For example, some new products are officially put into production lines. Although the procedures are in place, due to objective reasons such as lack of scientific operation and lack of necessary instruments for quality control, some products produced in the future will more or less have color deviations.Obviously, these products with color differences are "defective products". If there are too many "defective products", the profitability of enterprises will be greatly reduced. Therefore, from the perspective of cost control, the manufacturing enterprise must equip the inspection personnel or the first-line construction personnel with a professional colorimeter during the production process to scientifically measure the color difference of the product. Then continue to adjust and improve the manufacturing process to ultimately maintain the products color in one production line.

3. Colorimeter types

With the continuous advancement of testing technology, the colorimeter industry has also achieved leapfrog development. At present, the common types of colorimeters on the market include: colorimeter and spectrophotometer. Colorimeter can meet the common color measurement requirements. The colorimeter can be divided into handheld colorimeter and desktop colorimeter. The handheld colorimeter can directly read color difference. In addition, the handheld colorimeter is the easiest to carry around.The desktop colorimeter has large size. It is generally used in larger production enterprises. Although the handheld colorimeter is very small , it still has good repeatability.
