Colorimeter CS-400

A. Core technology

(1) Dual optical path design improves repeatability accuracy dE*ab≤0.03

The dual optical path design monitors the energy fluctuations of the light source

while measuring the sample signal, reducing interference during measurement, achieving higher measurement stability, and improving the instrument's measurement repeatability index to dE * ab ≤ 0.03. The measurement speed, accuracy, and stability of the instrument are ensured. Relevant technologies are protected by Chinese invention patents and American invention patents.

B. Product characteristics

(1) Ultra high repeatability accuracy:dE*ab≤0.03

Repeatability accuracy is an important index to describe the accuracy of a spectrophotometer. The excellent photoelectric testing system scheme ensures that the repeatability and accuracy of the DS400 series spectrophotometer have reached a level unmatched by similar products.

The repeatability evaluation of the DS400 series spectrophotometer adopts strict standards, presenting excellent repeatability and accuracy performance.

(1) More than 30 measurement parameters

l RGB,Lab,Reflectance,LCh,Hunter Lab,CIE-Luv,XYZ,Yxy

l Color difference(ΔE*ab,ΔE*cmc,ΔE*94,ΔE*00)

l Whiteness(ASTM E313-00,ASTM E313-73,CIE/ISO,AATCC,Hunter,Taube Berger Stensby)

l Yellowness(ASTM D1925,ASTM E313-00,ASTM E313-73)

l Blackness(My,dM),Color Fastness,Tint(ASTM E313-00)

l Color Density CMYK(A,T,E,M),Milm,Munsell, Opacity, Color strength

(2) Evaluate whether the color jumps, providing nearly 40 evaluation light sources

A、 B, C, D50, D55, D65 and other nearly 40 kinds of evaluation light sources could be chosen, almost covering all the color measurement index and light types in the industry.

(4) The base of the device was adjusted and the hardness of the Mo consortium was 9. The device's long-term stability was guaranteed

Compared with the existing products, there was no need to frequently adjust the DS400 series color difference instrument by hand when it was used. As long as it was placed on the base, the instrument would automatically adjust the overall function and accuracy of the instrument according to its own state and environment factors, making sure that the instrument was in a stable state and on standby at any time.

As for the existing products, there was no need for DS400 series to be tested frequently by hand when it was used. As long as it was placed on the base, the device would automatically adjust its overall function and accuracy according to its own state and environment factors, making sure that it was in a stable state and on standby at any time.

The white board in the base was the reference for the accuracy of the instrument. Through long-term investment and research, instrument has integrated zirconium material known as "artificial diamond" as a calibration whiteboard, with a surface Mohs hardness of 9. Because the material itself was as hard and stable as a diamond, it could guarantee that the surface of the board wouldn't be scratched, and it wouldn't change color with the change of temperature and humidity. Compared with the similar products both at home and abroad, the common industrial porcelain and even plastic were used as the white board for the reference. In this way, the stability and endurance of the equipment were further improved, and the performance of the equipment was guaranteed.
