Description
Condition
Used (Working Condition / Cosmetic Wear).
This dial indicator is in used condition with visible cosmetic wear (“rough” appearance) on the bezel and body, consistent with a life in a working machine shop. However, it has been tested and is functioning nicely. The spindle action is smooth, the return spring is strong, and the mechanism repeats correctly. It is sold as the Gauge Only (no box or accessories included).
Product Overview
The Mitutoyo 2959S is a specialised “One Revolution” dial indicator designed for error-free reading. Unlike standard indicators that can spin multiple times (leading to counting errors), this model’s measuring range is limited to 1.6mm.
This “One Rev” design effectively eliminates reading mistakes by ensuring the needle never passes the zero point more than once during a measurement. It features a high-sensitivity 0.01mm graduation and a unique shock-proof mechanism to protect the internal gears from sudden impacts. The dial face is balanced (0-100, but effectively sets up as 50-0-50) to clearly show positive and negative deviation from a set zero point.
Brand Information
Mitutoyo Corporation (est. 1934) is the global standard for precision measurement. The 2959S is a favourite in quality control departments because it removes the “human error” factor of miscounting spindle revolutions, making it perfect for Go/No-Go inspection fixtures.
