Mitutoyo 123-128 Disc Micrometer 3-4 Inch Range .001 Inch Graduation

The Mitutoyo 123-128 is a precision disc micrometer designed for measuring the thickness of paper, plastic, rubber, foam, and other thin materials. With a measuring range of 3-4 inches and .001 inch graduation, this tool provides accurate measurements where standard micrometers cannot reach or would damage delicate materials.

Key Features:

• Measuring range: 3-4 inches (75-100mm)
• Graduation: .001 inch (.01mm)
• Disc diameter: .787 inch (20mm) for reduced contact pressure on delicate materials
• Ratchet stop mechanism ensures consistent measuring force for repeatable results
• Includes standard bar for accurate calibration and setup
• Hardened and ground measuring faces for durability and accuracy

The disc-shaped measuring faces distribute pressure over a larger surface area compared to standard micrometers, making this tool ideal for measuring soft or compressible materials without deformation. The ratchet stop provides uniform measuring pressure, eliminating operator variation and ensuring measurement consistency.
