Principle
CR7 spectrophotometric color difference treasure is based on the principle of spectrophotometry, using a combined full-light spectrum LED Illuminant to illuminate the sample, and analyzing the reflected light into Light spectrum through a planar grating spectroscopic system. The silicon photodiode array sensor receives the optical signal and converts it into an electrical signal for processing, calculating Color values such as CIE LAB and color difference Delta E * ab. The integrating sphere design ensures diffuse illumination, reducing the influence of surface texture, and achieving stable and accurate color measurement.
Applications
Color quality control, Coatings, Plastics, Spinning & weaving, printing, Automotive, Electronics

CIE No.15、GB/T 3978、GB 2893、GB/T 18833、ISO7724-1、ASTM E1164、DIN5033 Teil7
Steps
1. Turn it on and warm up and correct it.
2. Measurement mode (single or average measurement)
3. Use the stabilizer to locate the sample and ensure that the measurement aperture is aligned
4. Trigger measurement, the instrument automatically collects data
5. View display results such as chromatic values, color differences, or reflectance
6. Save or export data to the storage system
Notice
• Avoid operating in extreme environments (temperatures above 0 to 40 ° C or Humidity above 85% RH)
• Ambient Temperature between -20 and 50 ° C during storage to prevent condensation
• Periodically calibrate instruments to maintain Measurement accuracy
• When using Original Accessories such as Powder Test Kits, follow the operating instructions
• The battery is charged only through the USB interface, and data transfer function is not supported
