Product Description

JDS Series RasGrating Length Measuring Machine

Feature
Simple structure instead of the complex optical system.
The realization of raster digital display makes it easy to use, the operation visual and convenient.
Software correction instead of manual point-by-point revising the decimeter scale, makes calibration convenient and fast.
Imported precision raster is used as measuring element, with satisfactory stability, lower heat value, corrosion resistance and contamination resistance.
Expansion coefficient of raster material is as the same as that of steel, having little influence by ambient temperature.
With inclination- Measuring sensor, software achieves real time compensation of Abbe error.
With temperature sensor, software achieves real time compensation of temperature effects.
