Digital Readouts (DRO)

Digital readouts are display units that work together with encoders to provide real-time position feedback. They convert encoder signals into easy-to-read measurements, helping operators achieve higher accuracy and efficiency in machining and inspection tasks. With a minimum resolution of 0.01 mm, DRO systems deliver precise and reliable data for lathes, milling machines, grinders, and other precision equipment.
