 YD200B |
| Features: Easy operation and versatility, combined with the computer to provide fast and results. The analyzer will compute four reference circles (the minimum zone, least squares, circumscribed and inscribed ), the out-of-roundness and eccentricity value relative to any of the four references are presented both quickly and reliable. The instrument is designed with compact structure, portability and convenient maintenance. It is yet shockproof so as to suit workshops. |
