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. Adopts spectral 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 Two. Technology Advantages
1).Uses CLEDs light source – spectrally balanced LED light source
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
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
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
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.
