Griptester MK2

The GripTester is highly reliable instrument for investigating accident sites, problem areas, and for predicting the safety of pavement surfaces.

Its light weight, robust construction and reliable performance make it the most deployable runway friction tester in the world. It is designed to be used in all seasons and has the ability to function in extreme weather conditions. The GripTester’s light tow bar pull and low center of gravity ensure safe, stable operation on winter and summer surfaces.

The GripTester is easy to use. An onboard computer handles daily calibrations internally and the unit can be towed by almost any vehicle and can use almost any laptop as a data collection computer. These features allow one person to quickly and comfortably prepare the GripTester, carry out a survey and create a runway/pavement friction report.
