Coolant Proof Micrometers

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.
