Starrett 12332 Dial Test Indicator Horizontal Dovetail

Product Description

The STARRETT 12332 is a horizontal-style dial test indicator built for precision measurement in metrology, machining, and inspection applications. It reads in a 0-100-0 bidirectional scale with a maximum measurement range of 0.20 mm per revolution and a dial graduation of 0.0020 mm, making it well suited for detecting minute surface variation, runout, and alignment error. The 1-1/4 inch diameter yellow dial provides high contrast readability in shop environments. A jeweled bearing mechanism supports smooth, repeatable needle response. The satin chrome finish resists corrosion and glare. Machinists, quality control technicians, and toolroom professionals are the primary installers and users of this instrument.

The STARRETT 12332 is used in horizontal indicator setups on surface plates, magnetic bases, indicator holders, and CMM fixtures. Its dovetail mount is the standard attachment method for most indicator arms and holders in precision metrology setups. The narrow body design allows positioning in tight locations on workpieces and fixtures. The indicator ships with two dovetail clamps, a contact point, and a protective case, making it ready for immediate deployment. It is applicable in both production and inspection environments where bidirectional surface deviation must be quantified accurately.

Key Features

• Bidirectional 0-100-0 dial scale with 0.0020 mm graduation for fine measurement resolution
• Jeweled bearing mechanism for smooth, repeatable needle movement and long service life
• High-contrast yellow dial face, 1-1/4 inch diameter, for clear reading under shop lighting
• Dovetail mount compatible with standard indicator arms, holders, and fixtures
• Contact point reverses automatically; replaceable and adjustable contact included
• Narrow body construction for access in confined measurement locations
• Satin chrome finish for corrosion resistance and reduced glare

Compatibility

Designed for use with standard dovetail indicator clamps and holders; two dovetail clamps are included. Compatible with STARRETT Series 3808 indicator accessories and setups requiring a horizontal-style dial test indicator with a dovetail mounting interface.

Installation Notes

Dial test indicators are installed by qualified machinists or metrology technicians and require no power source. Secure the dovetail shank firmly in the holder before taking measurements to prevent reading error from indicator movement. Avoid dropping or impacting the instrument, as shock can damage the jeweled bearing and affect calibration. Verify indicator calibration against a known reference before use in critical inspection work.
