JDS Series Optical Grating Length Measuring Machine

Features

->Imported precision grating linear is used as measuring unit, with good stability, lower heat dissipation, corrosion resistance and contamination resistance.
->Expansion coefficient of grating linear material is same as steel,  minimize the effect of ambient temperature.
-> Computer data processing technology, together with  one-dimensional measuring software, can carry out various measurements in high efficiency.
->Worktable can be moved, turned around and deflected in all directions, convenient for the inspection of various shapes of parts.
->With inclination detection sensor, software achieves real time compensation of Abel error.
->With temperature sensor, software achieves real time compensation of temperature effects.
