  • New comfortable wedge design that adapts to surface geometry
  • Embedded encoder with 12 steps/mm resolution
  • One connector type for simplified probe management
  • PCB-based sensor technology for excellent signal homogeneity
  • Integrated alarm LED directly on the probe
  • Detachable probe cable
  • Easy-replace wear protection with Teflon tape
  • Automatic configuration with the NORTEC 700 flaw detector
