Ⅰ、Key technology

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

The dual optical path design monitors light source energy fluctuations while measuring the sample signal, reducing interference during measurement, obtaining higher measurement stability and improving the instrument's measurement repeatability index to dE*ab ≤ 0.03, which guaranteed the measuring speed, accuracy and stability of the instrument.

（2）Innovative 5 micron thick nano-integrated optics

After intensive research, using nano-integrated optical devices as light splitters, only 5 micron thick optical devices can achieve nano-level light splitting ability, once again leading the direction of industry innovation, greatly improving the technical performance of products.

Ⅱ、Product features

（1）Over 30 Measurement Indicators

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

• Difference(ΔE*ab,ΔE*cmc,ΔE*94,ΔE*00)

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

• YI(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

（2）Evaluate whether the color is jumping light, and provide nearly 40 evaluation light sources

A, B, C, D50, D55, D65 and nearly 40 evaluation light sources can be selected, covering almost all the color measurement indicators and light source types in the industry.

（3）Contains SCI measurement mode

SCI refers to specular reflections that are generally used to study the properties of a color itself without regard to the surface gloss of the sample to which it is attached.

（4）Contains UV for fluorescent color measurement

This colorimeter still provide stable and objective reflectivity data for color measurement on surfaces containing fluorescent materials.

（5）Calibration base and zirconium reference with a Mohs hardness of 9 to calibrate the instrument, ensuring long-term stability

（6）The series supports 3 measuring apertures for selection（11mm，6mm ，3mm）

Large diameter (Φ11mm) dial to "M" file.

Small diameter (Φ6mm，Φ3mm) dial to "S" file.

（7）Built-in HD camera for clear observation of the measured area

This spectrophotometer can obtain an image of the measured area through the camera when measuring, which can clearly locate the measured area of the sample and avoid inaccurate measurement due to wrong area.

（8）Support WeChat applet, Android, Apple, Hongmeng mobile APP

• The DS no longer have to pass on the colour values of samples and physical objects, they can easily pass on colour data via WeChat.

• Users can find the most similar colours in multiple sets of colour cards.

•Users can create personal colour databases and enter information on colour cards for printing, paint and textiles. The colour libraries created can be uploaded to the cloud for easy colour processing with data sharing across multiple devices.

• Business users can create and manage their own colour card information library and colour recipes in the cloud, and share the information library and colour recipes to their own users through a unique invitation code.

（9）Use the powerful PC-based colour management system ColorExpert

The Windows color management system ColorExpert is included in the DS series colorimeter package, which can be connected to the colorimeter through Bluetooth or USB cable.

ColorExpert is a full-featured colour management software with four functional modules: My Colours, Colour Check, Colour Matching System and Personal Centre.
