Spi CMS170309004 Vernier Caliper 0-11.2 in Stainless Steel

Product Description

The SPI CMS170309004 is a stainless steel vernier caliper designed for precise linear measurement in trade, industrial, and inspection applications. It covers a measurement range of 0 to 11.2 inches (0 to 280 mm) with an accuracy of 0.0015 inches and a graduation of 0.001 inches (0.02 mm). The 2.5-inch jaw depth accommodates larger workpieces and deep-step measurements. Each unit ships NIST-traceable calibration certified and includes a protective case, making it ready for immediate use in quality control, fabrication, or field measurement tasks. Double set screws and a fine adjustment mechanism support repeatable, stable readings across extended work sessions.

This caliper is suited for machinists, pipe fitters, HVAC technicians, and other trade professionals who require reliable dimensional verification. The stainless steel construction resists corrosion in shop and field environments. The fine adjustment feature allows controlled, precise positioning of the sliding jaw, which is especially useful when measuring to tight tolerances on fittings, pipe ODs, conduit, or machined components. Both inch and metric graduations are provided, supporting dual-unit workflows common in mixed-standard environments.

Key Features

• Measurement range: 0 to 11.2 inches (0 to 280 mm)
• Accuracy of 0.0015 inches for reliable precision measurement
• 0.001-inch (0.02 mm) graduation for fine resolution readings
• 2.5-inch jaw depth for measuring larger or stepped workpieces
• NIST-traceable calibration certificate included
• Fine adjustment mechanism and double set screws for stable, repeatable positioning

Compatibility

Designed as a general-purpose vernier caliper for trade and industrial measurement applications requiring inch and metric graduations with NIST-traceable calibration.

Installation Notes

No installation is required for this measuring instrument. Before use, verify the caliper jaws close to zero and that the calibration certificate is reviewed for any noted offset values. Store the caliper in the included case to protect the measuring surfaces. Avoid dropping or forcing the sliding jaw, as this can affect calibration accuracy.
