Ensures a cost effective, safe, absolute means of meeting the minimum retroreflectivity requirements for traffic signs. Captures measurements for any type of retroreflective material and measures to ensure compliance with MUTCD minimum retroreflectivity requirements.
The RoadVista model 922 is a handheld sign retroreflectometer designed for use in the field. It is designed to measure the retroreflection (RA ) of road signs and other materials. The RoadVista model 922 is an integral component of any program to maintain minimum retroreflectivity levels.
ASTM has issued a new specification to require measurements to be performed at an observation angle of 0.5 degrees. The 922 is the perfect instrument for this addition. Utilizing the ASTM standard “annular” geometry, the 922 measures observation angles of 0.2 and 0.5 degrees simultaneously, with an entrance angle of -4 degrees. This patented (US Patent # 7,961,328) design allows you to know, with the press of a button, exactly how bright your sign will appear to most drivers.
A European version is available with a standard 0.33 degree observation angle and +5 degree entrance angle.
