Brown & Sharpe Dial Test Indicator – 0.03" Range, 0.0005" Graduation | Professional DTI with 6 Ruby Jewels, Satin Chrome Brass, 0-15-0 Dial, Dovetail Clamp & Storage Case for Precision Measurement

Professional Grade Precision & Resolution. Featuring a resolution of 0.0005" , accuracy: 0.0005" and a range of 0-0.030", this test indicator delivers precise, consistent readings in rigorous industrial environments. It serves as an essential dial indicator gauge for shaft alignment and flatness inspection, meeting the high demands of professional metrology

6 Jewel Movement for Smooth Operation: The internal mechanism is equipped with 6 precision ruby jewel bearings, which minimize internal friction. The precision jewel bearings and internal mechanism guarantee long-term durability and reliable readings without the need for oiling

Premium Brass Body & Long-Lasting Durability: Constructed from leaded brass with a satin chrome finish , the main body offers superior thermal stability, effectively resisting deformation caused by workshop temperature fluctuations to ensure long-term accuracy. The tungsten carbide contact point and stainless steel stem further enhance wear resistance

Accessories. The package includes a rugged ABS stackable hard case with high-density shock-absorbing foam. Complete with a specialized wrench for changing contact points and a dovetail clamp (1/4'' ) for securing the stem, it supports versatile mounting options, adapting flexibly to lathes, milling machines, or surface plates

Key Usage Instructions. To ensure maximum accuracy with the dial gauge indicator, the contact point should remain parallel to the measured surface (typically within a 15° angle) to avoid error. For flatness inspection, the contact ball should ideally maintain a 90° contact angle with the surface
