Retroreflectometers

A retroreflectometer being used.

The quality and performance of pavement markings have increased in recent years thanks to better paint and thermoplastic materials and higher performing glass beads. In addition, new marking types have improved in particular the performance during wet conditions at nighttime by allowing better run-off of water.

In parallel, cost of materials has increased having made road owners interested in knowing the actual amount of paint or thermoplastic applied while also having the ability to measure retroreflectivity. Combined with the industry-leading expertise of our technical service team, ENNIS-FLINT® by PPG DELTA® Retroflectometers and Marking Thickness Gauge can help road owners meet their needs.

DELTA® Retroreflectometers measure nighttime retroreflectivity
Delta Gauges and Retroreflectometers
DELTA® Retroreflectometers measure nighttime retroreflectivity of traffic control signs and pavement markings. Delta instruments are available to properly measure nighttime retroreflectivity or the thickness of dry, post-application pavement markings.
DELTA Marking Thickness Gauge
Our DELTA Marking Thickness Gauge is a digital devise for measuring the thickness of pavement markings dry, after application.
