Product Introduction

1. Product Overview

NJTT-301E Road Marking retroreflection measuring instrument is a professional measuring instrument used to measure the reflective performance of road marking. It supports the measurement of the retro reflective coefficient of markings under dry and humid conditions. The measured parameter is the reflectance coefficient R 'or specific brightness of the marked line, measured in mcd · lx-1 · m-2.
