Description

  • SERIES 293 — with Dust/Water Protection Conforming to IP65 Level

Features

  • World’s highest performing micrometer overall.
  • Extended battery life of approximately 2.4 years.
  • Ergonomic anti-slip frame cover and front panel for more comfortable hand-held measurements.
  • Ratchet thimble provides better operability for one-handed operation.
  • Oil-resistant material used for all plastic parts.
  • Models equipped with a Digimatic output port can form part of a statistical process control or networked measurement system. (Refer to page A-3 for details.)
  • Interface Input Tools are available that enable the conversion of measurement data to keyboard signals that are then directly input to cells in off-the-shelf spreadsheet software such as Excel. (Refer to page A-13 for details.)
  • Two types of constant-force devices are available: Ratchet Stop and Ratchet Thimble.
  • Measuring faces: Carbide.
