　　一，产品简介：

　　逆反射系数测量仪是依据国家相关标准研制开发的测量仪器，该仪器的特点是固定角度即观察角为0.2°，入射角-4°，在此几何条件下，测量各种逆反光材料的*亮值，这一测量值也是表征这类逆反射材料的*关键数据。该仪器采用精密设计的光学传感系统，配以32位单片微机作为数据处理核心，采用彩色液晶屏作为显示器件，汉字提示，清晰直观，简单易用。仪器内部自带可更换充电电池，使用方便。测试数据可以存储、查询。

　　Product introduction:

　　The retroreflectance measuring instrument is a measuring instrument developed in accordance with relevant national standards.The instrument is characterized by a fixed angle,that is,an observation angle of 0.2°and an incident angle of-4°.Under this geometrical condition,it measures various retroreflective materials*Brightness,this measurement is also the most critical data characterizing this type of retroreflective material.The instrument uses a precision-designed optical sensing system,with a 32-bit single-chip microcomputer as the data processing core,and a color LCD screen as the display device.The Chinese character prompt is clear,intuitive,and easy to use.The instrument comes with a replaceable rechargeable battery,which is easy to use.Test data can be stored and queried.
