英文简介：
The RoadVista Model 932 is a handheld retroreflectometer designed for use in the field, laboratory or QA/QC environment. It is designed to fully characterize the retroreflection (RA) and retroreflected night-time (CIE1931xy) color of road signs, high visibility safety clothing and other materials.
This patented (US Patent # 7,961,328) design allows you to know, with the press of a button, exactly how bright your retroreflector will appear to drivers, and determine if the color falls within the defined color box. The adjustable entrance angle and observation allows for complete characterization of most retroreflectors, including full high-visibility clothing retroreflective testing to EN471 and ANSI107. The Model 932 comes standard with a Bluetooth wireless interface and USB computer interface both allowing for remote operation of the in-strument and data logging. The internal memory has the capacity to store more than 32,000 measurements. The sensitive light sensor meets ASTM E1709 and ASTM E2540 require-ments with the CIE standard human eye response. Our world-class pho-tometric filter fit is unmatched by the competition and al-lows extremely accurate measurements of other colors us-ing the single white reference standard with no correction factors.
