　　逆反射系數(shù)測(cè)量?jī)x是依據(jù)國(guó)家相關(guān)標(biāo)準(zhǔn)研制開發(fā)的測(cè)量?jī)x器，該儀器的特點(diǎn)是固定角度即觀察角為0.2°，入射角-4°，在此幾何條件下，測(cè)量各種逆反光材料的*亮值，這一測(cè)量值也是表征這類逆反射材料的*關(guān)鍵數(shù)據(jù)。該儀器采用精密設(shè)計(jì)的光學(xué)傳感系統(tǒng)，配以32位單片微機(jī)作為數(shù)據(jù)處理核心，采用彩色液晶屏作為顯示器件，漢字提示，清晰直觀，簡(jiǎn)單易用。儀器內(nèi)部自帶可更換充電電池，使用方便。測(cè)試數(shù)據(jù)可以存儲(chǔ)、查詢。

　　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.
