DS-200 Series Colorimeter

Stable and reliable instrument for color difference detection
Repeatability accuracy is up to: dE*ab < 0.03

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. Related technologies are protected by Chinese invention patents and US invention patents.

(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. Relevant technologies are protected by Chinese invention patents.

(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
DS-200 series 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
Compared to existing products, the DS-200 series spectrophotometer does not require frequent manual calibration when in use. Simply place it on the calibration base and the instrument will automatically calibrate the overall instrument function and accuracy according to its own state and environmental factors, ensuring that the instrument is always in a stable state and ready for use.
The white plate in the calibration base is the basis of the instrument’s work. Through long-term investment and research, CHNSpec has integrated zirconium material as the calibration white plate, with a Mohs hardness of 9. As the material itself has the hardness and stability comparable to diamond, the surface of the calibration white plate will not be scratched and will not change colour with changes in temperature and humidity. This is a further improvement in the stability and durability of the calibration whiteboard compared to similar foreign and domestic products that use common industrial ceramics or even plastic as calibration whiteboards, ensuring the performance of the instrument.

Calibrated white plate
(artificial diamond zirconium material)
·Mohs hardness: 9
·Spectral reflectance >90%
·No discolouration due to changes in
temperature and humidity
·No discolouration by oxidation
·Ultra-high strength without scratching
(6)The DS-200 series supports 3 measuring apertures for selection(11mm,6mm,3mm)
Rotate to switch the caliber. Say goodbye to the tedious manual screw fixing method.
Large caliber ( Φ 11mm) Dial to “M”.
Small caliber ( Φ 6mm, Φ 3mm) Dial to the “S”.

(7)Built-in HD camera for clear observation of the measured area
DS-200 series 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-200 series colorimeter can be connected to a variety of mobile phones via a rich mobile app.
• Users 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-200 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.
