Road surface friction measuring device / DF tester
Measuring the skid resistance value of road surfaces. A compact road surface friction measuring device that is easy to carry, simple to operate, and minimizes individual differences among operators.
The "Road Surface Friction Measurement Device / DF Tester" is a portable dynamic friction measurement device that can be used in narrow spaces, curves, and on slopes. It detects the relative deformation of a measuring disc equipped with a flywheel that rotates via a drive motor and three rubber sliders. It measures the sliding resistance between the rubber sliders and the measuring surface. This product is used not only in Japan but also by various organizations and companies overseas, including research institutions such as universities, road companies, automobile manufacturers, tire manufacturers, airports, and monorails. 【Features】 - Short measurement time, easy operation, and no individual differences among operators - Compact and easy to transport, can be transported in a wagon - Automatic watering through a watering pipe from the water tank (accessory) - Easy comparison with previously measured data using the included software - Power supply can be from a car battery (DC12V) or AC100V using an A/D converter (sold separately) *For more details, please refer to the PDF document or feel free to contact us.
