The BX-A portable reflectance coefficient measuring instrument is designed in strict accordance with national standards GB/T18833-2012 and JT/T612-2004 traffic industry standards. The instrument adopts 32-bit main control module and embedded real-time operating system, which has the characteristics of accurate measurement and small error. At the same time, it has built-in large-capacity storage unit to solve the cumbersome problems such as on-line recalibration of similar products on the market, and it is truly ready for immediate use. Used to facilitate measurement; In addition the instrument uses a lithium battery as the main power supply, rechargeable.
Second, the measurement principle
Under a certain geometric condition, the brightness value of the reflective material produced per unit area under the unit illumination. It is represented by the coefficient of retroreflection, unit: cd/lx/m2.
