Many instruments are used to measure force. The most important is the force gauge or dynamometer. It's in fact a load sensor with a display. Those gauges are often mounted on a test stand or directly integrated in the frame. Some of them are: Force meter or Newton-meter spring balance spring scale torque wrench bathroom scale strain gauge (Measures force within a material) For examples of instruments that measure force visit the Related Link, A newton meter, measured in N (Newtons) A ruler can be used A dynamometer is a tool for measuring force.
