      CS-280
        Spectral colorimeter is the colorimeter which adopts the theory of spectrophotometer. It is widely used for plastic, printing, paint, ink, textile, dyeing and other industries for color management. It could measure the target L*a*b, L*c*h and the sample △E and △Lab value.
      Part One. Instrument Introduction
      1. Spectral colorimeter : The highest precision colorimeter
      2.Adoptsspectral measurement working theory which greatly improve the accuracy of colorimeter
      3. Patented technology guarantees the measurement stability
      4. Obtain national metrology certification
      5. Ergonomic Design
      Instrument girth radian designs according to human palm so we could test data for a long time. Superior leather design increases the friction in case of fingers sliding.
      6. Mass storage memory : It could save 100 pcs targets and 200 pcs samples.

      Part Five. Application


      Part Two. Technology Advantages
      1).Uses CLEDs light source – spectrally balanced LED light source (Patent NO. : ZL2013107548347)
      LED light source that has balanced intensity across visible spectrum avoids the spectral deficiency in certain parts of the spectrum in common white LEDs, which guarantees the speed and accuracy of the measurement results. This research has been published in national leading optical journal Chinese Optics Letter.

      2).ETC-Every Test calibration technology (Patent NO. : ZL20130373360.1)
      Currently, most instruments use standard white boards for calibration. When white board is damaged, the instrument’s accuracy or precision will no longer be guaranteed. In CHNSpec’s spectrophotometers, it uses innovative ETC(Every Test Calibration); standard white board is included in the optical system, and therefore has reliable accuracy and repeatability in every measurement.

      3).Automatic gloss compensation technology (Patent NO. :ZL201310511357.1)
      Different gloss or different instrument’s light source or observation conditions will largely affect the color measurement. The automatic gloss compensation technology guarantees the accuracy of color measurement data for surfaces of different gloss. This research is published in international leading journal Optik.

      4).Innovative light splitting SCS optical engine (Patent NO. : ZL201210337619.2)
      Adopt innovative single-grating-dual-light-paths light splitting system: SCS optical engine , creates the best measurement repeatability for portable spectrophotometers in the industry, and guaranteed accurate measurement of surface color of materials.

      Part Three. Instrument Details

      Part Six. Guarantee
      1).Longest Guarantee Time

      a. One Year Guarantee Time.
      b. If testing data is not correct, we can do refund.
      c. We will provide testing report for every device to assure the authority of the data and it will save the calibration cost for 1 year.
