Friction testing for any surface - two devices, one mission:

reliable, high-resolution, convenient friction data.

— TOW-BEHIND CFME

GripTester MK2

Pull-behind continuous friction measuring device.

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.

Technical Specifications
Type: Tow-behind continuous friction measuring equipment (CFME)
Weight: 180 lbs — built with durability and portability in mind
Measurement Principle: Braked wheel, 15% fixed slip ratio
Data Resolution: One friction measurement every 8 inches
Test Tire: 10 × 4-5 smooth tread friction test tire (ASTM E1844-08)
Water System: Self-wetting system; built-in tank custom built for your vehicle, or a removable water bladder with fixed or variable flow valve
Software: Road Base / Air Base; records and charts measurements from a built-in computer, transferred by USB to any laptop
Construction: Weather-proof, modular design for quick and easy component swapping
Approvals: Approved by the FHWA and certified by the FAA and ICAO

Micro GripTester

Portable push mode continuous friction measuring device.

The Micro GripTester’s touch screen display guides the user through the friction test procedures and allows operators to save their results directly onto the inbuilt hard drive or onto a removable hard drive. The Micro GripTester utilizes integrated GPS to allow all surveys to be overlaid on a map providing a graphical Grip Number display.

The Micro GripTester’s compact, lightweight design allows it to be used as a one man operation. It can measure the skid resistance of any paved area or paint markings at a walking pace. No user calibration is required and it is not affected by bends, cambers or inclines and any horizontal slope is measured and reported so as not to skew the results. These features allow for ease of use and ensure accurate and consistent measurements regardless of user or condition.

Technical Specifications
Type: Walk-behind continuous friction measuring equipment (CFME)
Weight: 50 lbs; splits into two carrying cases and fits in the back seat of a pickup truck
Measurement Principle: Braked wheel — construction nearly identical to the MK2, so data correlates 1:1 with MK2 data
Data Resolution: Friction coefficient as frequently as every 2 inches
Test Tire: 10 × 4-5 smooth tread friction test tire (ASTM E1844-08)
Standard: ASTM E3304 — walking speed continuous friction measurement
Calibration: No user calibration required; unaffected by bends, cambers or inclines
Data & Mapping: Integrated touch screen computer; GPS friction maps to pinpoint problem areas; USB transfer to any capable device
Compliance: UK CAA CAP 437 helideck friction testing

Replacement Parts In Stock

The GripTester’s open structure and modular design make maintenance simple. We stock replacement parts and components, so a quick swap gets you back to testing instead of waiting on overseas shipping.

Options & Upgrades

Tailor your unit to your operation: the Runway Alignment System (RAS) keeps the GT on a straight, repeatable path down the runway with GPS guidance, and tanker trailer and custom water tank options extend your continuous testing range.
