Mitutoyo 2991A-10 Series 2 Dial Gauge, ISO Type, Back Plunger Design, One Revolution, Shockproof, 0.008" Range, 0.0001" Graduation

Unlike many other dial indicators, the one-revolution dial indicator literally shows the entire spindle travel or range as one sweep of the hand, eliminating the possibility of reading errors due to miscounting multiple revolutions. With one-revolution dial indicators, "within tolerance" and "out-of-tolerance" can never be misinterpreted.

Features:

• The crystal is hard coated for durability and scratch resistance.
• Approximately 40% lighter than the conventional dial indicator.
• Provided with an improved resistance to shop floor contaminants such as water and dust.
• Due to the spindle bushing being offset from the stem, spindle movement will not be hindered or jammed when clamping along the stem.
• A pair of limit hands are provided for quick and easy tolerance judgment (GO/±NG).
