Colorimeter's Introduction and classification

 

Colorimeter, widely used in the field of color management in plastics, printing, paint ink, textile and garment industries. According to Lab, Lch principle of CIE color space, the measurement shows the color difference △ E and △ Lab value of the sample and the measured sample. Category: colorimeter based on performance parameters, accuracy and use of the scope of requirements can be divided into: 1, handheld colorimeter - also known as color

 

Colorimeter, widely used in the field of color management in plastics, printing, paint ink, textile and garment industries. According to Lab, Lch principle of CIE color space, the measurement shows the color difference △ E and △ Lab value of the sample and the measured sample.

 

Category: colorimeter based on performance parameters, accuracy and use of the scope of requirements can be divided into:

 

1, handheld colorimeter - also known as color colorimeter, can read the data directly, can not even computer, without software. Easy to use, cheap, but less accurate. The general area of ​​color management is widely used.

 

2, portable colorimeter - also known as portable spectrophotometer, can read data directly, but also with the computer, with software. Small size, easy to carry, high precision, affordable.

 

3, desktop colorimeter - also known as desktop spectrophotometric color matching instrument, a reading window, even when using the computer color measurement, color software, with high-precision color measurement and color matching function, larger, stable performance, higher prices .

 

main feature:

 

1, Automatically compare the color difference between the model and the seized product, output three sets of data of CIE_Lab and color difference data of △ E, △ L, △ a and △ b after colorimetric to provide reference scheme of color matching.

 

2, with a sample and a single two measurement modes to meet the needs of different places of measurement, simple operation, accurate measurement.

 

3, the instrument is portable. A battery and external power supply two kinds of power supply, convenient and practical.

 

4, equipped with USB expansion interface, you can connect with the computer display. Correlation analysis method: automatically compare the color difference between the model and the seized product, and output three groups of data of L, a, b and color difference data of △ E, △ L, △ a and △ b after colorimetric analysis. △ E the total color of the size △ L + that white, △ L - said black △ a + that reddish, △ a- that is green △ b + that yellow, △ b-blue
