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.
