Introduction

The Continuous friction tester (CFT) is used to measure the surface friction coefficient of highway or runway of airport.

Constructions

The whole system comprised the measuring unit, 3-wheel walking unit, road surface temperature sensor and non-contact environmental temperature sensor, specialized test software, and water-spray system and wheel-lift system can be optional equipped. The 3-wheel trailer is connected to the front tractor through a tow hook to quickly test the road friction coefficient.

Features & Advantages

High sturdy structure and innovative design make the JT-CFT03 can perform road friction coefficient detection under almost all road conditions

Wide application range, not only meet the road test standards of most countries, also meet the FAA Standard.

Multi-language option for test software, better meets the operation requirements of different countries and areas.

Touch screen operation of test interface

Real time display of parameters: walking speed, test distance, friction coefficient value, SFC conversion value, air temperature
