Spi MS170111012 Electronic Caliper 0-1 Inch 0.0005 Resolution

Product Description

The SPI MS170111012 is a short-range electronic caliper designed for precise outside diameter measurements in toolroom, inspection, and light machining environments. It reads from 0 to 1 inch with a resolution of 0.0005 inches and an accuracy of 0.0008 inches, making it well suited for applications where fine dimensional verification is required. The caliper is calibrated and ships with a Short Form Certificate, confirming it meets documented measurement standards. Power comes from a CR2032 battery, which is included. Licensed machinists, quality control technicians, and precision tooling specialists are the primary users.

This caliper is intended for outside diameter measurement applications where a compact, short-range instrument is appropriate. Its 0 to 1 inch range targets small-part inspection tasks common in production QC, tool and die work, and bench inspection setups. The overall length of 3.15 inches keeps the instrument easy to handle in confined workspaces. Inside diameter jaws are not included, so this unit is purpose-built for OD and similar external measurements. It is not designed for depth or step measurements unless the tool geometry specifically supports it.

Key Features

• Resolution of 0.0005 inches for high-precision dimensional readings
• Accuracy rated at 0.0008 inches across the full measurement range
• Calibrated with Short Form Certificate included for traceable measurement documentation
• CR2032 battery included — no additional power source required out of the box
• Compact 3.15 inch overall length suits tight workspaces and small-part inspection
• Outside diameter application focus; no inside diameter jaws

Compatibility

Designed as a precision OD measurement tool for use in toolroom, inspection, and light machining applications where a 0 to 1 inch range electronic caliper is required.

Installation Notes

This instrument requires no installation but should be handled and stored according to standard metrology practices. Before use, verify the caliper zeroes correctly with jaws fully closed and confirm the battery is seated properly. Avoid exposing the unit to coolants, oils, or abrasive debris that could affect slide movement or electronic function. Calibration verification against a known gauge block is recommended before first use in a documented inspection process.
