The 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 comparative measurements with the Swiss National Institute of Metrology (METAS).
