3NH color difference treasure CR7 (basic version) single diameter 8mm fixed focus
SE
Chromatic value: MAV/SCI, ΔE * ab within 0.1 (after preheating correction, the average value of 30 whiteboard measurements at intervals of 5s)ΔE * from < 0.4 (MAV / SCI)
Using built-in silicon photodiode array (dual row 24 groups) sensor, imported whiteboard, Repeatability Delta E * ab can be easily controlled within 0.1. CR7 spectroscopic color difference Baoqiang's performance configuration and excellent inter-instrument difference make color measurement more professional while ensuring the conformity of measurement data of multiple devices.
