Excellent repeatability and inter-stage difference
Repeatability ΔE*ab≤0.025, difference between units≤0.25, accurate and reliable data, ensuring the consistency of measurement data from multiple devices for color matching and accurate color transfer
Dual-column high-precision CMOS array design monitors the energy fluctuation of the light source while measuring the sample signal to reduce interference during measurement and obtain higher measurement stability. Large-area dual-array sensor provides higher spectral response sensitivity, ensuring high standards of instrument measurement speed, accuracy, stability and consistency of inter-stage differences
Automatic Calibration Technology
The instrument is placed on an intelligent calibration base, and the instrument can be automatically calibrated by the whiteboard on the base without human intervention. It changes the status quo of traditional instruments that must be calibrated manually on the white board. The white board made of ZrO2 with reflectivity R%>90% is used as the calibration standard, which ensures good mechanical strength and weather resistance, and no scratches and discoloration will occur in long-term use
