Product Introduction

1. Overview

The NJTT-101C road sign retroreflective measuring instrument is an instrument used for on-site measurement of the photometric performance (retroreflective coefficient R ') of retroreflective materials. It is a handheld optical instrument with simple operation and convenient use. It can be used for traffic safety management and relevant departments such as highways, railways, and aviation to conduct on-site measurement of retroreflective signs (reflective films, etc.), measure the reflective performance of reflective signs on truck type motor vehicle bodies, and monitor the reflective quality of retroreflective materials produced to ensure that retroreflective sign materials meet the requirements of relevant standards and regulations. The instrument consists of an optical system, detection amplification system, power supply and control system, display system, and instrument calibration block.

The NJTT-101C road sign retroreflective measuring instrument is designed in accordance with the standard ISO3864 and GB/T 26377-2010, GB/T18833-2012, and JT/T612-2004, JJF 1809-2020, GB21861-2014. To facilitate the calibration of instrument readings, a set of calibration blocks for calibrating instrument readings is also provided to ensure the accuracy and reliability of instrument measurements; Display the instrument with a touch screen display meter; Using lithium batteries as the power source.
