— THE PROBLEM WE SOLVE
Skidding Accidents
Shouldn't Happen
And with GripTester, they won't.
GripTester is a state-of-the-art piece of continuous friction measuring equipment (CFME). It helps prevent a range of safety and performance issues related to surface grip, primarily focusing on road and runway conditions. GripTester collects a friction data point every 8 inches, providing an accredited, high-resolution friction report of your pavement surface. By ensuring adequate grip, the GripTester contributes to safer driving and landing conditions, thereby reducing the risk of accidents, enhancing overall transportation safety, and aiding in the maintenance of infrastructure by identifying areas that require resurfacing or repair.
8 Inches
A friction measurement every 8 inches — high-resolution data across your entire surface.
One Operator
Works on inclines, around corners, and at any speed with a one-person crew.
550+
Airports worldwide rely on GripTester for accredited friction reporting.

Our Areas Of Expertise
AirportsFAA PART 139
Friction testing is essential for FAA Part 139 compliance. Aircraft overruns are always damaging and sometimes disastrous. Skidding on contaminated surfaces is the most common cause of such incidents. The most effective way of preventing them is to carry out regular surveys with a recognized runway friction tester and act promptly on the results. If an overrun does occur, a timely friction survey report can be used to establish the airport’s due diligence.
RoadsDOT/FHWA
The GripTester’s light weight, robust construction and reliable performance make it the most deployable highway friction tester. It can collect a measurement every 8 inches — around turns, on inclines, and at any speed. Almost any work vehicle can tow the GripTester along and nearly any laptop can be used as a data collection computer. A one-man crew can comfortably survey up to 100 miles of road on a single tank of water.
HelidecksCAP 437
The Micro GripTester is CAP 437 compliant with a compact, lightweight design, allowing it to be deployed by a one-man crew. It can measure skid resistance of any paved area or paint marking at a walking pace with no user calibration required. The built-in screen makes it effortless to create a friction map of your testing space. The device can be split into two smaller carrying cases, making it the most portable friction testing option on the planet.
MotorsportsNASCAR/F1
Grip is the difference between a record lap and a trip into the wall. GripTester is trusted at the highest levels of motorsports — from NASCAR ovals to Formula 1 circuits — to map friction across every turn of the track. Rubber buildup, resurfacing, and track treatments all change how a surface grips; regular surveys give race control and tire engineers like Michelin the data they need to keep competition fast and safe.

NASCAR All-Star Race: How GripTester Was Used
The Friction 1 and GripTester team joined NASCAR and Goodyear’s Advanced Engineering Group at the historic North Wilkesboro Speedway before the NASCAR All-Star Race to assist in ensuring optimal track conditions and safety for drivers.
High-resolution friction data, captured in walk mode around every turn — where rubber buildup matters most.
