Features
This instrument test result accurate and repeatable, simple to operate, can be used in laboratory or field, is used to measure the in-night brightness of road marking made of retroreflective material simulating under illumination from the headlights of vehicles driving on road, i.e, the in-night brightness observed by the driver in vehicle. The measured parameter is the nighttime retroreflective brightness coefficient RL & QD value.
Relative Standards：
GB/T 26377-2010, GB/T 16311-2009, JJG059-2004
Main features:
Press buttons for operation.
Make calibration the boards in White & Yellow to proceed measuring markings.
5-inch bright touching screen, real-time display of temperature and humidity.
One-button measurement, no need to repeat calibration in the same day.
Long standby time, fast charging.
