LA-302Road Marking Road Line RetroreflectometerUsage OverviewThe instrument is designed and developed with reference to relevant international technical documents and current national standards and norms in China. It meets the requirements of No. 72 published by the International Lighting Commission (CIE),ASTMD4061-94, DIN67520, 67521 of Germany, GB/T 26377-2010 Reverse Reflectometer of China, GB/T 16311-2009 Quality Requirements and Monitoring Methods of Road Traffic Markings, JJG 059-2004 Verification Regulations of Reverse Reflectometer.Product DescriptionMeasurement principleThe geometric condition of the retroreflective marking instrument is to simulate the scene observed by the driver in the cab when the headlamp illuminates the marking made of the retroreflective material on the road at night.The angle between the optical axis of the headlamp and the normal line of the road surface (reference axis) becomes the incident angle (beta), which is set at 88.76 degrees. The angle between the optical axis of the headlamp and the reverse light is called the observation angle (alpha), which is set at 1.05 degrees. The light source and optical system are projected to the marking line according to the incident angle beta. The size of the measured marking line is 200 X 95 mm. The reflected light from the marking line is emitted to the filter equipped with V(lambda) according to the observation angle alpha of 1.05 degree. The measured value is displayed on the measuring value display after processing, that is, the measured value of the inverse reflection coefficient.SpecificationObservation angle of the instrument1.05 degreesIncident angle is beta88.76 degreesComplementary angle1.24 degreesLight Source Color Temperature2856K+50K (CIEA Light Source)Detectorsilicon diode + V (lambda) rectifier, meets therequirements of CIE standardspectrophotometric observer spectral optical efficiency V (lambda)The measurement range of L retroreflectiveCoefficient R'is 0-3000 MCD lx-1 m-2Battery Continuous Working Time72 HoursData Storage10,000 Test InformationScreen4.5 "854x480Computer ConnectionTF Storage CardCharging220VAC 50HZ; DC8.4VPower supplylithium (6600 mah)Protection LevelIP54Working temperature- 15 C ~ + 50 COperating humidit10-90%, no condensationVolume (length x width x height)450mm x 132 mm x 132 mmNet weight5kgOur AdvantagesInstallation and training · If buyers visit our factory and check the machine, we will teach you how to installand use the machine, and also train your workers/technician face to face. · Without visiting, we will send you user manual and video to teach you to install and operate.After Service · One year guarantee for whole machine. · 24 hours technical support by email or callingAny questions, please contact me without hestitation, welcome your inquiry!Price can be negotiatedour customerCompany Profile ` Cangzhou Lovely Group Co.,Ltd. is a professional manufacturer specializing in Testing Equipment,Universal Testing Machine ,Asphalt Tester,Test Moldsand Soil Road Lab Tester,supply verious type of products .....
