Product Description
Road Marking Road Line RetroreflectometerProduct DescriptionProduct Basis and StandardsThe 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.Measurement 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 valueis displayed on the measuring value display after processing, that is, the measured value of the inverse reflection coefficient R'.ParametersObservation 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 Time 72 HoursData Storage10,000 Test InformationScreen4.5 "854x480Computer ConnectionTF Storage CardCharging220VAC 50HZ; DC8.4VPower supply lithium (6600 mah)Protection Level IP54Working temperature - 15 C ~ + 50 COperating humidit10-90%, no condensationVolume (length x width x height)450mm x 132 mm x 132 mmNet weight5kgApplicationContact USCangzhou Lovely Technology Co., Ltd. is specialize in Nondestructive Test Instrument and Material Test Machine over 10 years, Without advanced technologies and best customer service, Our product has exported to more than 100 countries and regions, which win favorable comments from customers worldwide.We adhere to the high standards of product quality, strict requirements, adopting the world-class production equipment, advanced management and production experience, developing the high-quality testing equipment.We have has strong sales team and a comprehensive service process to serve end customers around the world.If you have any inquiry or concern,Sales and after service department will reply you within 24 hours.Our Customers and patent certificatePacking & DeliveryWhy Choose us ?get our in-time reply via email or telephone or instant messenger;get best product with excellent quality and competitive price;One year guarantee for whole machine 24 hours technical support by email or calling teach you to install and operate,always enjoy our considerable & full-side after-sales service; feel very convenient since we can help you sourcing and ship products from different factories via one shipment, which to a large extent save your time and cost; easily make the payment via West Union, Paypal, T/T for small value order;
