Metrology is the science of measurement. We use it every day to ensure consistency across our vast catalog of products. Our CMMs (coordinate measuring machines) take state of the art measurements. We also measure surface finish, contour and roundness. We have in-house metallurgy capabilities, which enable us to check microhardness and microstructure. Our measurement processes are so precise that we have the ability to measure to one millionth of an inch.
