• Excellent accuracy of (1.1+0.6L/600)μm with 0.1μm/0.4μm resolution/repeatability.
  • High-accuracy Height Gage incorporating a wide range of measurement functions.
  • To achieve best-in-class accuracy, a highaccuracy reflective-type linear encoder and high-accuracy guide are used.
  • Measurement can be implemented by icon based commands that also support easy one key operation.
    Perpendicularity (frontal) of 5μm and straightness of 4μm are guaranteed.
  • The TFT LCD provides excellent visibility and operability.
  • Pneumatic full/semi-floating system allows adjustment of air-cushion height.
  • Basic statistical functions are provided and, additionally, RS-232C data output provides the option of evaluating measurement data externally with SPC software on a PC.
  • For precision Black Granite Surface Plates, refer to page E-51.
  • Backup/Restore of data and measurement part programs can be implemented using USB storage devices (FAT16/32 format compatible).
