一、逆反射系數(shù)測量儀產(chǎn)品簡介：
逆反射系數(shù)測量儀是依據(jù)國加相關(guān)標(biāo)準(zhǔn)研制開發(fā)的測量儀器，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，測量各種逆反光材料的*亮值，這一測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，簡單易用。儀器內(nèi)部自帶可更換充電電池，使用方便。測試數(shù)據(jù)可以存儲、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.
