This LA-302D marking retroreflective coefficient measuring instrument is a portable field measuring instrument used to measure the retroreflective characteristics of road markings. The characteristic researched by LA-302D instrument is mainly to simulate the brightness of road markings visible to the driver under the illumination of motor vehicle headlights at night, and the measured parameter is the retroreflective coefficient of night light.Functional characteristics:
 Support fast measurement (retroreflective coefficient value measured within 3 seconds)
 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
 Support real-time broadcast of measurement data
 Support real-time broadcast on the spot, and directly print out the test
 results on the spot through the printer
 Use the touch keyboard to input English and characters
 Support real-time display of on-site temperature and humidity
 English menu operation mode can be opened to foreign customers to facilitate their use
 Support smart standby management, the system automatically enters sleep state when there is no operation
 Portable instrument with small dimensions and light weight
 Support for calibrating two colors at one time before testing in the same field environment, no need to calibrate each time you test or encounter different colors
