republic of south africa Reverse reflection marker measuring instrument

The pavement marking retroreflectivity meter is a professional measuring instrument developed and manufactured by our company for measuring the retroreflective performance of road markings.

Product Description

Purpose

Road marking retroreflection coefficient measuring instrument, is a specialized measuring instrument developed and produced by our company for measuring the retroreflective performance of road markings. The measured parameter is the retroreflection coefficient R’ of the marking R’, Unit mcd·x -1 ·m -2 。The instrument is easy to operate, reliable in measurement, suitable for both laboratory and field measurements. It is a professional equipment for measuring the retroreflective performance of road markings used by production, quality supervision, engineering construction, and supervision units.

Main functions and features, standards and specifications:

This instrument mainly refers to relevant international technical documents, as well as current national standards and

specifications. It conforms to the International Commission on Illumination (CIE) publication No. ,American 72 ASTM D4061-94, German DIN67520,67521 and China’s 《Retroreflection Measurement GB/T26377-2010 Instrument》 GB/T16311-2009 《Quality requirements and monitoring methods for road traffic markings》, JJG( Transportation) 059-2004《Verification regulations for retroreflection measuring instruments》 and other relevant standards. Measurement principle

The geometric conditions of the retroreflective marking measuring instrument simulate the situation when a car drives on a highway at night, the car headlights illuminate the road markings made of retroreflective materials on the road surface, and after reflection,

RP-R11 are observed by the driver in the cab. 驶时,汽车前照灯照射在路面上的逆反射材料制作的标线,经其反射后, 被驾驶室内的司机观察到的情景。
