RL&QD Road Retroreflectometer marking line retroreflection measuring instrument
PRoduct description
All-weather measurement, day or night, outdoors or indoors.
The Reflectivity Tester is easy to operate and displays the retroreflection coefficient value in intuitive numbers.
The Retroreflectance Measuring Instrument is equipped with a set of standard versions, which are calibrated by data transfer and have high accuracy.
The measurement geometric conditions are an observation angle of 1.05° and an incident angle of 88.76, which are in line with the industry standards of the Ministry of Transport.
The instrument is small in size, light in weight and easy to carry.
Technical indicators:
Observation angle (α): 1.05°;
Incident angle (β): 88.76°;
Light source color temperature: 2856K (i.e. CIE A light source);
Detector: Silicon diode + V (λ) corrector, in line with the requirements of CIE standard photometric observer spectral luminous efficiency function V (λ);
The measurement range of retroreflection coefficient (R′): 0～1999mcd·lx-1·m-2;
Display: 31/2 digits (LCD digital display);
Power source: Rechargeable lithium-ion battery.
Main Functional Characteristics
