Moment of Inertia Measurement Instruments

Space Electronics offers many types of instruments to measure moment of inertia (MOI) with some combining weight and center of gravity measurements as well. Our largest instrument can measure objects weighing up to 22,000 pounds (10,000 kg). Our smallest instrument measures tiny mechanisms weighing less than 1 gram. These instruments test moment of inertia with the highest precision without even knowing the center of gravity.
