Colorimeter DS-400

（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.

（2）Innovative 5-micron thick nano integrated optics                      

Innovation is the soul of instrument. Using nano integrated optical devices as spectroscopic devices can achieve nano level spectroscopic capabilities with only 5 micron thick optical devices, once again leading the direction of industry innovation, greatly improving the technical performance of the product.

 Relevant technologies are protected by Chinese invention patents.

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 DS-400 spectrophotometer have reached a level unmatched by similar products.

The repeatability evaluation of the DS-400 spectrophotometer adopts strict standards, presenting excellent repeatability and accuracy performance. 

2.  More than 30 measurement parameters        

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

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

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

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

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

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

3.    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 DS-400 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 DS-400 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.

5.  DS-400 could provide 10 different sizes of measurement            

In order to make it convenient for the customer to measure the samples of different sizes, the DS-400 color contrast instrument could support 10 different sizes for the customer to use: stable:Φ11mm，Φ10mm，Φ6mm，Φ5mm，Φ3mm， dexterous: ▽11mm，▽10mm，▽6mm，▽5mm，▽3mm，which can be flexibly used in different use and testing conditions.

6.There was a high definition camera in the room, which could clearly observe the area being tested      

DS-400 could get the image of the tested area through the camera when measuring. It could clearly locate the area where the sample was tested, so as to avoid the wrong area from being detected.

7. It also supported WeChat applications, such as Android, apple and omnipotent phone APP      

• The DS400 color detecting device could connect all kinds of mobile phones through rich mobile applications.

• The customer didn't need to send the sample color and object, and could easily send the color data through WeChat.

• The user could find the most similar color among several sets of color cards.

• The users could create a personal color database and enter information about printing, paint, spinning and other colors. The color library could be uploaded to the cloud, and many devices could share data, so that color processing was more convenient.

• Enterprises could establish and manage their own color card information library and color formulas in the cloud, and share them with their own users through unique invitation cards.

8.   Using the powerful color management system ColorExpert on PC*       

• The Windows color management system ColorExpert was attached to the DS400. It was connected to the DS400 through Bluetooth or USB.

• ColorExpert was a color management software with four functions: my color, color detection, color system and personal center.

• In the "my color" function, the user could collect or build the color library he or she needed in hundreds of other colors which were shared by themselves. The PC software and the mobile APP could share the same account, and the data of the color library could follow the account, so that the information of the computer and the mobile could be in sync.

• In the "color detecting" function, the user could use the computer software to adjust, measure and set up a light detecting device. The users could use the colors in the cloud data bank as samples to test the color difference, and check the color difference picture, the color difference picture, the data of the standard samples, and the test report of the data they wanted.

• In the color system, it could provide a more convenient and efficient color matching process for the users. After measuring the color of the sample with the instrument, the system calculated the formula in the formula center and adjusted the color automatically, and finally achieved an accurate match. It was suitable for computer automatic color matching in paint, paint, printing, spinning and other fields.

• In the "personal center", the user could edit his own personal information, search or delete the connected instrument information, manage the downstream users, and manage the color library that was shared with the downstream users.
