Máy đo phản xạ Roadvista 933 Retroreflectivity Goniometer System
The primary light sensor meets ASTM E1709 requirements with the CIE standard human eye response in conjunction with the CIE illuminant “A” lamp. The photometric filter accurately measures different colors without the need to calculate correction factors. The color detector features a 3-channel RGB sensor used to generate CIE1931 color coordinates.
The user interface features a high resolution color touch screen. A separate graphics co-processor provides quick, intuitive response as well as clearly rendered text and images for easy viewing of pertinent data.
The unit can be operated as a stand-alone unit, in which case the internal memory has the capacity to store readings and accompanying data for more than 30,000 measurements in non-volatile flash memory. Additionally, the 933 can be controlled over USB via simple ASCII commands to automate multi-measurement situations. USB drivers for Windows, Mac, and Linux are available, as well as sample Windows software utilizing Excel that demonstrates macro control.
