Portable Friction Measurement

micro GripTester has been developed to measure the skid resistance of any paved area or paint markings at walking pace. micro GripTester is based on the same measuring principles as the GripTester which is used world wide to measure skid resistance at traffic speeds.

The device can be used in many applications such as:

• pedestrian areas
• road, pavement surfaces
• paint markings
• reinstatements
• man hole covers
• accident sites

micro Grip Tester is a cost effective and dynamic alternative to Pendulum spot measurements.

• One man operation (weight < 21Kg)
• Continuous measurement (every 25mm)
• Self-wetting
• Stable
• Same measuring principle as GripTester
• Same measuring tyre as GripTester
• Integrated GPS
• No user calibration required
• Measurement not affected by bends, cambers or inclines
• Horizontal slope is measured and reported
• Annual Certification
