Spi CMS220519027 Electronic Point Micrometer 0-1 in

Product Description

The SPI CMS220519027 is an electronic point micrometer designed for precision inside measurement in tight or restricted areas where standard flat-anvil micrometers cannot reach. With a measuring range of 0 to 1 inch and a resolution of 0.0001 inch, it delivers the accuracy required for critical dimensional inspection. The ratchet thimble provides consistent measuring force, reducing operator-to-operator variation. Both the spindle and anvil are ground to 30-degree included angles, making this tool suitable for measuring grooves, keyways, and small bores. It is calibrated to ASME B89.1.13 standards and used by machinists, quality technicians, and tool-and-die professionals.

This micrometer is suited for shop-floor and inspection-room use in manufacturing, toolmaking, and precision machining environments. The 32 mm throat depth allows clearance for workpieces that would otherwise be inaccessible to conventional outside micrometers. A rotating spindle and digital counter with data output capability make it compatible with statistical process control workflows. It ships with a plastic storage box and a 3V CR2032 lithium battery included.

Key Features

• Electronic digital readout with 0.0001 inch resolution and digital counter display
• Ratchet thimble ensures repeatable, consistent measuring force
• 30-degree point angles on both spindle and anvil for groove and keyway access
• Carbide anvil and SUS420F spindle material for wear resistance and long service life
• 32 mm throat depth for clearance on recessed or hard-to-reach features
• Data output port supports SPC integration; positive lock nut secures the reading
• Calibrated to ASME B89.1.13; includes plastic storage box and CR2032 battery

Compatibility

Designed as an OEM-style precision measurement tool for use in applications requiring point-contact micrometry across a 0 to 1 inch range, conforming to ASME B89.1.13.

Installation Notes

Point micrometers are a hand tool requiring no installation; however, calibration verification against a known standard is recommended before first use and at regular intervals per shop quality procedures. Store in the included plastic box and avoid contact between the carbide points and hard surfaces when not in use. Battery replacement uses a standard 3V CR2032 lithium coin cell. Data output connections should follow the instrument manufacturer wiring specification for the specific interface cable used.
