Spi CMS220519018 Electronic Tube Micrometer 0-1 in

Product Description

The SPI CMS220519018 is an electronic tube micrometer designed for precise outside-diameter measurement of tubing, pipe walls, and similar cylindrical workpieces. It covers a measurement range of 0 to 1 inch with a resolution and graduation of 0.0001 inch and a stated accuracy of plus or minus 0.0001 inch, making it suitable for high-tolerance inspection work. The rotating spindle is fabricated from SUS420F stainless steel, and the anvil is tipped with carbide for wear resistance. A ratchet thimble ensures consistent measuring force across repeated measurements. Calibrated to ASME B89.1.13 standards, this instrument is appropriate for quality control, fabrication verification, and incoming inspection tasks performed by machinists, pipefitters, and metrology technicians.

The CMS220519018 is suited for shop floor and inspection room environments where tube wall thickness or outside diameter must be verified to tight tolerances. The tube-style anvil geometry allows the instrument to seat correctly on curved surfaces that a standard flat anvil cannot register accurately. A positive lock nut holds the thimble position during reading or transfer measurement. The unit ships in a fitted plastic storage box to protect the measuring faces during transport and storage.

Key Features

• Electronic digital readout with 0.0001 inch graduation and resolution
• Carbide anvil tip resists wear during repeated contact with hard workpiece surfaces
• Ratchet thimble provides consistent, repeatable measuring force
• Rotating spindle in SUS420F stainless steel for corrosion resistance
• Positive lock nut secures thimble position for transfer readings
• Calibrated to ASME B89.1.13 dimensional metrology standard
• Includes fitted plastic storage box

Compatibility

Designed as an OEM-style precision measuring instrument for use in standard tube and pipe inspection applications where a 0 to 1 inch electronic micrometer with a tube anvil configuration is required.

Installation Notes

Tube micrometers require no installation but should be zeroed and verified against a known standard before use. Keep measuring faces clean and free of chips or debris before contact. Store in the supplied plastic box when not in use to protect the carbide anvil and spindle faces. Calibration intervals should follow the facility quality management schedule in accordance with ASME B89.1.13 or applicable shop standards.
