Spi MS170309016 Electronic Inside Diameter Caliper

Product Description

The SPI MS170309016 is an electronic inside diameter caliper designed for precision measurement in manufacturing, machining, and inspection environments. It covers a measurement range of 0 to 1 inch with a resolution of 0.0005 inches and an accuracy of 0.0008 inches, making it suitable for close-tolerance work on bores, holes, and internal features. The unit ships calibrated to Short Form Certified standards and includes inside diameter jaws for direct bore measurement. It is powered by a CR2032 battery, which is included. Machinists, quality control technicians, and tool and die professionals are the typical end users.

This caliper is built specifically for inside diameter measurement applications. It is well suited for shop floor use, inspection stations, and tool crib environments where repeatable, traceable readings on internal dimensions are required. The Short Form Certified calibration makes it appropriate for quality management workflows where documented measurement traceability is part of the process. The maximum metric equivalent measurement is 30 millimeters, allowing use in shops that work in both inch and metric standards.

Key Features

• Measurement range of 0 to 1 inch with 0.0005 inch resolution for fine-tolerance inspection
• Accuracy of 0.0008 inches for reliable close-tolerance readings
• Includes inside diameter jaws designed for bore and hole measurement
• Ships calibrated to Short Form Certified standards for quality-managed environments
• Battery-powered operation using a CR2032 cell, included with the caliper
• Maximum metric range of 30 millimeters for dual-standard shop use

Compatibility

Designed as an OEM-style precision measuring instrument for inside diameter applications in machining, manufacturing inspection, and quality control environments where a range of 0 to 1 inch is sufficient.

Installation Notes

Installation of a battery is required before first use; insert the included CR2032 cell according to the polarity markings inside the battery compartment. Zero the caliper against a known reference before taking measurements to ensure reading accuracy. Handle the jaws carefully to avoid nicks or burrs that can affect measurement repeatability. Calibration should be verified periodically according to your facility's quality management schedule.
