Dynemech Anti Vibration Table DIT-AHL-GN has natural frequency in the range of 1-2 Hz along with selF-levelling feature. Available self-levelling accuracy is ± 0.015 mm and ± 0.15 mm with minimum setting time, depending upon the application requirement. membrane air springs are used which damps most of the incoming vibrations above 10 Hz. Level difference on top of the granite surface due to any load change and the equipment is compensated within milliseconds. This table has a high levelling accuracy.
