WebT2GO Portable Continuous Friction Measuring Equipment, CFME. SARSYS-ASFT has developed a highly versatile friction tester, T2GO, which can measure friction on any surface both dry and contaminated. It is ideal for measuring in areas where it might be difficult to get access to with a larger trailer or vehicle type friction tester. WebThe DFT measures surface friction as a function of speed (20, 40 and 60 kilometers per hour for this study). The result is a dimensionless value known as the friction number (Fn). In this study, 40 kph produced the most repeatable results, so the friction values are expressed as DFT (40). Higher values indicate better friction properties. gumtree dogs for rehoming scotland
