LGH
• This series has achieved very high accuracy combined with a resolution of 0.01/0.005 μm (according to model), practically equivalent to that of a laser interferometer, and a wide measuring range of 10 mm.
• A compact body design makes a significant contribution to a downsizing of this gage itself, which is best suited for calibration/evaluation of master gages as well as measurement of high-precision parts and as a length measuring sensor incorporated into high-precision positioning/control units.
• A low measuring force model is available for those applications where measurement of easily deformed or damaged workpieces is required.
• Every LGH Series gage is bundled with a dedicated counter.
