Calibration and Precision Angular Positioning

Industries requirement to rotate and position components to ever increasing accuracies require positioning devises and instrumentation to operate an order higher to not only achieve these accuracies but to verify performance via calibrations traceable to international standards.

RPI is not only a world leader in the supply of these very high precision positioning devices but design and manufacture equipment capable of verifying their performance with angular positioning capabilities of less than 0.00027 degrees, 1 arc second or 0.0000047 radians and radial geometry of less than 0.0001mm.
