Standards: GB/T 26377-2010, GB/T 16311, JJG 059-2004, JTG F80-1-2017, ASTM D4061-94, DIN 67520, 67521
The marking retroreflectometer is a portable on-site measuring instrument used to measure the night-time light retroreflective coefficient of road markings, that is, the RL value, in units of mcd/m²/lx. It is suitable for laboratory environment and can also be used for on-site measurement.
Features
Support fast measurement (measure the value of retroreflection coefficient in about 3s);
Support simple calibration procedure;
Large battery capacity, long standby time, and supports fast charging;
Support high-brightness LCD transparent touch screen, the operation interface can be seen clearly under light;
Support multiple measurements to calculate the average value;
Support to store more than 99999 pieces of inspection data information, including measurement data, operator, road section information and inspection time, etc.;
Support 8G SD card data storage, and support data storage in Excel form, export to computer through U disk function;
Support real-time broadcast of measurement data;
Support to lock on-site inspection data, and print out the inspection results directly through the printer;
Use the touch keyboard to input Chinese characters, English and characters;
Support on-site real-time display;
English menu operation mode can be opened to foreign customers to facilitate their use;
Support intelligent standby management, the system automatically enters the sleep state when there is no operation;
Smaller size/lighter weight;
In the same on-site measurement environment, all colors can be calibrated at one time before testing, and there is no need to calibrate different colors separately before each measurement.
