This portable roundness tester adopts a permanent magnet suspension spindle, which balances portability and high precision with a rotary accuracy of 0.5μm, meeting the detection needs of most industrial on-site components. It has an IP54 protection grade, which can adapt to the workshop environment with dust and oil stains, and will not be affected by common industrial site pollution. It is equipped with a DC12V lithium battery that can work continuously for 8 hours without external power supply, meeting the needs of outdoor and mobile detection. The whole machine weighs only 12kg and can be carried by a single person, which greatly improves the flexibility of on-site inspection. It is also equipped with a lightweight touch tablet that can analyze data offline, solving the problem of difficulty in real-time data analysis during on-site detection.
