Non-Contact / Online Color Sensor CRX-50 / CRX-51 / CRX-52 Introduction

Others | 2019-06-18 18:26:56

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.
