The Model 930C Laboratory/Field Retroreflectometer provides a convenient, handheld way to inspect new retroreflective materials and signs as well as determine degradation resulting from weathering at many different observation and entrance angles. Its accuracy is more than adequate for over 90% of all field inspections.
The system includes three ranges of sensitivity, an entrance angle attachment and two sets of standards of all colors in engineering and high intensity types. The optical head observation angle is continuously adjustable from 0.2° to 2.0°. The light sensor meets the requirements of a match to the CIE standard human eye. A photometric filter fit allows accurate measurements of other colors when the 930C is standardized using the white calibration reference.
Power the system via the standard 110/220 VAC supply or the included DC battery pack. If field measurement is needed for high-mounted traffic signs, the Model 907-30 extension pole kit is recommended.
