• Digimatic micrometer equipped with a constant / low measuring force mechanism. The measurement-value hold function automatically retains the data at a specified measuring force. (Pressing with a larger force than the specified measuring force does not affect the measurement result.)
• It is suitable for measuring flexible workpieces such as electric wire, paper, and rubber.
• Non-rotating spindle reduces workpiece deformation.
• Measuring faces: Carbide tipped
