FT-S Microforce Sensing Probe

The newest generation of FemtoTools FT-S Microforce Sensing Probes are microforce sensors capable of measuring forces from 200 millinewtons (0.2 N) down to sub-nanonewtons (10-9 N) along the sensor’s probe axis. Both compression and tension forces can be measured. The outstanding long-term stability and low signal drift guarantees significantly higher measurement accuracy than any other force sensing system in this force range. The accuracy of the FemtoTools SI-traceable calibration process is ensured by comaparitive measurements with the Swiss National Institute of Metrology (METAS).

Sensor tip options:

  • Flat silicon tip with a tip size of 50 µm by 50 µm
  • Pointy tungsten probe tip with a tip radius smaller than 5µm, 2µm or 0.1µm
  • Spherical glass tip with a point radius of 25 µm (learn more)
  • Spherical ruby  tip with a point radius of 125 µm (learn more)
  • Diamond nanoindenter tips (e.g. Berkovich, Conical, customized geometry)

Compatible Measurement Systems
