標線逆反射系數(shù)測量儀特點
點擊次數(shù):1545 更新時間:2019-05-20

描述:
反光標線亮度,上用逆反射系數(shù)來表示,單位mcd/lx/m2。其物理意義是:在單位光照條件下,單位面積上產(chǎn)生的亮度值。將儀器置于被測標線的上面,該儀器以數(shù)字的形式顯示出逆反射系數(shù)值,它反映了行車條件下司機對標線反光亮度的客觀評價。該儀器由測量主機、電源、充電器、標準板組成。


Third, the description:
The inverse cursor line brightness is expressed internationally by the coefficient of retroreflection, in mcd/lx/m2. Its physical meaning is: the brightness value produced per unit area under unit illumination conditions. The instrument is placed on top of the measured marking line. The instrument displays the value of the retroreflection coefficient in digital form, which reflects the objective evaluation of the driver's reflection brightness on the marking line under driving conditions. The instrument consists of a measuring host, a power supply, a charger, and a standard board.
特點
能不分白天、夜間、野外、室內(nèi),全天候測量;
儀器操作簡單,以直觀的數(shù)字顯示出逆反射系數(shù)值;
儀器配備一套標準板,采用數(shù)據(jù)傳遞方式進行標定,準確度高;
測量幾何條件為觀察角1.05°,入射角88.76°,符合國家標準《道路交通標準質量要求和檢測方法》;
儀器體積小,重量輕,攜帶方便

Fourth, characteristics
◆It can be measured all day, day, night, field, indoors;
◆The instrument is easy to operate and displays the value of the retroreflection coefficient in an intuitive number;
◆The instrument is equipped with a set of standard boards, which are calibrated by data transmission method with high accuracy;
◆The measurement geometry is the observation angle of 1.05° and the incident angle of 88.76°, which conforms to the national standard “Quality requirements and testing methods for road traffic standards”;
◆The instrument is small in size, light in weight and easy to carry
