The Nano Tribometer (NTR3) is a unique instrument for characterizing the tribological properties of a wide range of surfaces at low contact pressures. The system provides accurate and extremely linear measurement of both normal and tangential forces  employing an elastic unique quad beam cantilever combined with high-resolution capacitive sensors. The Nano Tribometer combines the resolution of an Atomic Force Microscope (AFM) with the stability, robustness and ease-of-use of a pin-on-disk tribometer. Extending the applications of a pin-on-disk system, NTR3 is capable of forces in the range of a few ┬ÁN and displacements in the range of hundreds of microns. All in all, NTR opens up new dimensions of nano- and micro-tribology.
