STT-101C type inverse reflection sign measuring instrument

First, an overview

STT-101C type inverse reflection sign measuring instrument is an instrument which can be used in the field to measure the photometric properties (inverse reflection coefficient R ') of inverse reflection material. It is based on the CE Windows operating system under the control platform, with 32 bit high-speed processor core, man-machine dialogue interface, portable photoelectric instrument, easy to operate, practical.

Two, the scope of application

1, traffic safety management and highway, railway, aviation and other relevant departments of the reverse reflection logo on the spot detection;

2. Measurement of the reflective performance of the vehicle body of the vehicle;

3, reverse reflective material manufacturers for the production of reflective material quality monitoring.

Three, design standards

The instrument is based on the "GB/T 26377-2010 Retroreflectometer" GB/T and 188833-2012 "road traffic" reflective film related standards and design, conforms to the GB21861-2014 standard, "motor vehicle safety and technical inspection items and methods". In order to facilitate the calibration instrument display value, it is also equipped with a set of calibration blocks to ensure the accuracy and reliability of the instrument measurement values.
