Space Electronics is the world’s number one manufacturer of aerospace mass properties measurement instruments. Since our founding in 1959, we have sold more Moment of Inertia and Center of Gravity instruments than any other company. One reason for our success is our unique technology. We invented the force restoration concept of CG measurement and the inverted torsion pendulum method of measuring MOI. We are the originator of the spherical gas bearing spin balance machine, which uses two force transducers to determine both Product of Inertia and CG offset in a single run. Another reason for our success is the extraordinary reliability of our products — some of our instruments have been used daily for more than 20 years without malfunctioning. Our instruments are the most accurate in the world. Because of our unique technology, we have a moment accuracy of 1 part in 300,000. Most mass properties measuring instruments manufactured by other companies use load cell technology, which is only capable of an accuracy of 1 part in 2,000. Our extraordinary accuracy allows us to manufacture a single instrument that can accurately measure objects whose weight ranges from 100% to less than 3% of full scale. Other manufacturers must supply several different size instruments to accomplish the same goal.
