Brief Introduction
Color sensor made by CHNSpec is designed to measure color online. It can be widely used on paper production line, textile production line, tape/film production line, etc to measure color for the large size and flat materials.
The color sensor is with built-in calibration tile for auto calibration. Instrument adopts LED light who has a very long lifetime to make maintain much easier.
