Spi 13-997-2 Dial Indicator Base Kit Magnetic Base

Product Description

The SPI 13-997-2 is a dial indicator base kit designed for precision measurement tasks in mechanical, HVAC, and industrial service environments. It pairs a dial-style indicator with a magnetic base, allowing technicians to secure the assembly to ferrous surfaces for hands-free readings. The indicator features a 0-100 dial reading with 0.001 inch graduation increments, providing fine resolution suitable for runout checks, shaft alignment, and surface flatness verification. The 2.25-inch dial diameter offers clear readability at close working distances. The kit ships in a fitted carrying case, keeping components protected and organized between uses. Typically installed and operated by machinists, millwrights, or HVAC alignment technicians.

This kit is suited for residential and light commercial service calls where precise positional measurement is required. Common applications include checking blower shaft runout, verifying motor shaft alignment, inspecting bearing seat geometry, and confirming component flatness before assembly. The magnetic base attaches firmly to any flat ferrous surface, allowing the indicator to be repositioned quickly without additional fixturing. The fitted case makes it practical for field use by technicians who carry tools between job sites.

Key Features

• 0.001 inch dial graduation for high-resolution measurements
• 0-100 dial reading range on a white-face dial
• 2.25-inch dial diameter for easy reading at working distance
• Magnetic base style for tool-free attachment to ferrous surfaces
• Furnished in a fitted case for organized transport and storage
• Kit includes magnetic base and SPI indicator as a matched set

Compatibility

Designed as a general-purpose dial indicator kit compatible with standard measurement and alignment tasks on ferrous machine surfaces across industrial and trade service applications.

Installation Notes

This tool is operated by qualified technicians familiar with precision measurement procedures. Before use, ensure the magnetic base is fully engaged and the indicator stem is perpendicular to the surface being measured to avoid cosine error. Clean the contact surface of debris before securing the base to prevent false readings. Handle the indicator with care to avoid dropping, as internal gear mechanisms are sensitive to impact.
