It is equipped with intelligent calibration base, can carry out automatic white board calibration, professional grade standard white board reflectivity R% ≥95% , good surface uniformity, high stability, can obtain repeated accurate data.
5、New fashion appearance design based on ergonomics
The hand-held position and the position of the measuring button are carefully designed to meet different holding habits, smooth and fine surface, derived from the professional appearance treatment technology.
6、Excellent interstation and repeatability
The repeatability ΔE * ab ≤0.038, the Inter-instrument Error ΔE * AB ≤0.38 data is stable and reliable, which ensures the consistency of the data measured by multiple devices, and can be used for color matching and accurate color transfer.
7、Multi-color measurement space and observation light source
