CS-288 Spectro Colorimeter

Spectral colorimeter adopts same working theory as spectrophotometer.It is widely used for plastic, printing, paint, ink, textile, dyeing and other industries.It can measure the target L*a*b, L*c*h and color difference value.

Part One. Instrument Introduction

1. Spectro 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. Large 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 (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.Every Test calibration technology (ETC) (Patent Right No.: ZL20130373360.1)

For now most instruments use standard white tile for calibration.When white tile is damaged, the instrument’s accuracy or precision will no longer be guaranteed. In CHNSpec’s spectrophotometers, we adopt innovative ETC(Every Test Calibration); standard white board is included in the optical system, and therefore has reliable accuracy and repeat-ability in every measurement.

3.Automatic Gloss Compensation Technology (Patent Right No.: ZL201310511357.1)

Gloss will greatly affect the measurement of color. Our instrument adopts automatic gloss compensation technology which guarantees the accuracy of color measurement value for surfaces of different gloss. This research finding is published in international leading, SCI included journal, Optik.

4.Innovative light splitting SCS optical engine(Patent Right No.:ZL201210337619.2)

Adopt innovative single-grating-dual-light-paths light splitting system: SCS optical engine which creates the best measurement repeatability for portable spectrophotometers and guarantees accurate measurement of surface color of materials.

5.Longest Device Guarantee Time

handheld colorimeter

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.
