Product Description

Product Description

LA-3A Portable Spectrophotometer Color Difference Detector Colorimeter with UV SCI/SCE BLE
 

The LA-3A colorimeter is a compact and lightweight portable colorimeter. The 45/0 geometrical optical structure is consistent with the visual perception color value Z, which can exclude the specular light on the textured surface, and is suitable for the measurement of the brightness factor and chromaticity coordinates of traffic signs, markings, and reflective films.
