RT3 Tow Hitch

We specialize in

continuous friction measurement equipment (CFME)
for road and runway surfaces



Four Versions

RT3 Grip
RT3 Under Truck
RT3 Flight
RT3 Curve

The RT3 indicates all changes in road surface friction and runway surface friction due to any surface contamination including rubber, pavement aging and changes in weather, including rain, ice and snow.


The patented RT3 design, originally developed for use in auto racing (Indy car and Le Mans 24 hours), is precision USA technology and generates a friction result with very high sensitivity and repeatability (98+%).

This revolutionary design is rugged enough to cope with the most severe weather and road conditions.

Data is available in the vehicle and can be directed simultaneously to a remote site – real time!

Extensively independently tested in the USA, Canada, Japan and Sweden (See “Reports”).

The RT3 Flight is the latest technology to be accredited by the FAA in May 2010 as a CFME (Continuous Friction Measurement Equipment) meter for runway friction measurement use within Appendix 4 of Advisory Circular 150/5320-12C
