Spi CMS160809136 Mechanical Tube Micrometer 0-1 in

Product Description

The SPI CMS160809136 is a mechanical tube micrometer designed for precise inside-diameter measurement of tubes, pipes, and thin-walled cylindrical workpieces. It delivers a measuring range of 0 to 1 inch with a graduation of 0.0001 inch and a stated accuracy of 0.0001 inch, making it appropriate for quality-control and inspection work where tight tolerances matter. The A-style anvil and ratchet stop thimble provide consistent seating and repeatable spindle pressure across measurements. Both the anvil and spindle contact faces are carbide-tipped to resist wear during regular production use. The instrument ships calibrated and includes a short-form certificate of calibration.

This micrometer is used in metrology, machinist inspection, and QC environments wherever tube-wall or bore measurements must be held to precise tolerances. Typical applications include checking tubing used in HVAC, refrigeration, hydraulic, and pneumatic assemblies. It is appropriate for shop-floor inspection by machinists, quality technicians, or field technicians verifying tube dimensions against engineering specifications. The included case protects the instrument during storage and transport between job sites or inspection stations.

Key Features

• 0 to 1 inch measuring range with 0.0001 inch graduation
• 0.0001 inch accuracy for tight-tolerance inspection work
• A-style anvil suited for tube and thin-wall cylindrical measurement
• Ratchet stop thimble ensures consistent, repeatable spindle pressure
• Carbide-faced anvil and spindle for extended wear resistance
• Ships calibrated with a short-form certificate of calibration and protective case

Compatibility

Designed as a general-purpose mechanical tube micrometer for inspection of tubes and thin-walled cylindrical parts within a 0 to 1 inch measurement range.

Installation Notes

This instrument is a precision measuring tool, not an installed component. Handle with care to avoid dropping, which can shift calibration. Clean contact faces before use and store in the included case when not in service. Recalibrate periodically per your facility quality plan or applicable metrology standards.
