• ABSOLUTE electromagnetic induction linear encoder system is introduced.
  • Due to the low measuring force, these calipers are ideal for measuring elastic workpieces such as plastic parts and rubber parts that standard calipers cannot measure accurately.
  • Allows fine feeding easily by using thumb roller.
  • Displacement of main scale jaw is 0.3mm.
  • Measuring force: 0.49N to 0.98N (0.5gf to 1.0gf)
  • Absolute type. (Refer to page D-8 for a description of Absolute measurement.)
  • Allows integration into statistical process control and measurement systems for models with measurement data output connector.
    Refer to page A-3.
