Spi CMS220519003 Electronic Outside Micrometer 2-3 in

Product Description

The SPI CMS220519003 is a digital outside micrometer designed for precise external dimensional measurement in the 2 to 3 inch range. It delivers an accuracy of plus or minus 0.00020 inches and carries an IP65 rating for protection against dust and water ingress, making it suitable for demanding shop and field environments. The measuring faces are carbide-tipped for wear resistance and long-term measurement integrity. A ratchet thimble provides consistent measuring force, reducing operator-to-operator variation. This instrument is calibrated to ASME B89.1.13 standards and is used by machinists, quality control technicians, pipefitters, and mechanical contractors who require verified dimensional accuracy on finished or installed components.

The CMS220519003 is suited for precision measurement tasks in manufacturing, fabrication, and mechanical service work. It covers any external measurement between 2 and 3 inches, including shaft diameters, tube wall stock, and machined fittings. The rotating spindle and lever-style lock nut allow secure measurement hold once a reading is taken. A CR2032 lithium battery is included, powering the digital readout for immediate use out of the box. This micrometer is appropriate for both shop bench work and on-site dimensional verification.

Key Features

• Digital readout with plus or minus 0.00020 inch accuracy
• IP65-rated housing resists dust and water splash for harsh environments
• Carbide-tipped measuring faces resist wear over extended service life
• Ratchet thimble ensures consistent, repeatable measuring force
• Lever-style lock nut holds spindle position for secure readings
• Calibrated to ASME B89.1.13 standards; CR2032 lithium battery included

Compatibility

Designed as an OEM-style precision measurement tool for external dimensional work in the 2 to 3 inch range, compatible with standard micrometer stands and holders designed for that frame size.

Installation Notes

No installation is required for handheld measurement tools. Before use, verify zero calibration at the 2 inch reference point per the manufacturer procedure. Store in the provided case away from temperature extremes and magnetic fields that could affect digital accuracy. Battery replacement requires a CR2032 cell; follow standard ESD precautions when handling the battery compartment.
