    GL RETROREFLECTOMETER 4.0 SRS - GL Optic | ENG
    Top suppliers of retroreflection and chromaticity testers include Gamma Scientific/RoadVista, Instrument Systems, and GL Optic, which offer advanced, high-precision equipment for traffic signs, markings, and automotive applications. Other key providers include Everfine, Labtron, and Lighten Traffic, catering to both laboratory and field testing needs. 
    Key Suppliers & Equipment Types 
    • Gamma Scientific / RoadVista (USA): Known for handheld retroreflectometers used in traffic safety, providing both retroreflection (
      RAcap R sub cap A
      𝑅𝐴
      ) and nighttime color (
      CIE1931xycap C cap I cap E 1931 x y
      𝐶𝐼𝐸1931𝑥𝑦
      ) analysis.
    • Instrument Systems (Germany): Provides the RMS series for high-precision, automated retroreflection measurement for automotive and sign applications.
    • GL Optic (Germany): Offers the GL RETROREFLECTOMETER 4.0 SRS, which offers full spectral analysis for road signs and safety devices.
    • Everfine (China): Specializes in optical tests for automotive lighting, including reflective devices, offering both laboratory and online solutions.
    • Labtron (International): Supplies portable reflectivity testers that analyze color characteristics and reflectivity for materials science.
    • Lighten Traffic (China): Focuses on multi-angle retroreflection meters for traffic signs and vests.
    • UTSTesters: Offers wholesale retroreflection and chromaticity testing machines. 
    Common Applications 
    • Road Marking and Signs: Measuring night-time visibility and chromaticity (ASTM E 1709, E 1809).
    • High-Visibility Clothing: Testing in accordance with ISO 20471.
    • Automotive Components: Testing retroreflective lighting. 
    Key Considerations
    When selecting a tester, look for compliance with ASTM standards, portable versus laboratory setups, and the ability to measure multiple angles, as noted by Lighten Traffic.
