STT-101A inverse reflection sign measuring instrument

First, product overview

Retroreflective Signs measuring instrument is also called traffic signs inverse reflection coefficient measurement (test) instrument is used to measure the traffic sign materials inverse reflection coefficient (R) of the special instruments.

STT-101A retro reflection measuring instrument by Beijing Traffic Engineering Instrument Research Institute for development and production, material production units, quality supervision departments, construction and supervision units for quality control and inspection mark retroreflective materials.

The design of the instrument conforms to the International Commission on illumination (CIE) provisions of NO.54 specification, and relevant standards: refer to other countries such as the United States ASTM E808-01 ", ASTME809-00" retroreflective description standard "retro reflector optical performance measurement", "reflective film ASTME810-00 inverse reflection coefficient test method"; Germany DIN67520-1994. The performance of the instrument in accordance with the provisions of GB/T 26377-2010 "Retroreflectometer", meet the national standard of China GB/T 18833-2012 "road traffic regulations" reflective film measurement requirements, conform to the standard GB21861-2014 "motor vehicle safety and technical inspection items and methods".

Two, the main technical indicators

1 observation angle (alpha):0.1 degrees to 2 degrees within the scope of continuous adjustment, the reading accuracy of 0.002 degrees;

2 incidence angle (beta):-40 degree to 40 degree of continuous adjustment, the degree of reading is 1 degrees;

The 3 light source color temperature: 2856K (the standard A light source);

4 detector: silicon diode, after the filter is modified to meet the requirements of CIE standard photometric observer spectral light efficiency V (a);

5 of the sample detector aperture angle: 12';

6 inverse reflection coefficient measurement range: 0 ~ 1999cd - lx-1 - m-2 (points x 1, x 10, x 100 third);

7 display: three and a half digital display table;

8 DC power supply: input AC voltage 50Hz, 220V; output DC voltage in the range of 1 ~ 6V continuously adjustable, precision is 0.02V.
