The Mitutoyo Series 340 Outside Micrometer features a wide measuring range enabled by interchangeable anvils, designed for precise dimensional verification. Equipped with an electromagnetic rotary sensor for position detection and an IP65 water/dust protection rating (applicable on models up to 300 mm / 12 in), these micrometers ensure reliable performance in demanding industrial environments. A ratchet stop is integrated to maintain constant measuring force across applications.
- Wide Measuring Range: Utilizes interchangeable anvils to cover extensive measuring spans within a single instrument.
- Durability & Protection: IP65 water and dust resistance (for models up to 300 mm / 12 in) protects internal components against coolant, water, oil, and dust.
- Constant Measuring Force: Equipped with a standard Ratchet Stop mechanism to ensure repeatable and consistent measurement accuracy.
- Carbide-Tipped Spindle: Measuring faces of the spindle are carbide-tipped for enhanced wear resistance.
- Data Output & Connectivity: Supports SPC data output functionality, with optional connection cables and U-WAVE wireless systems available.
- Position Detection: Incorporates an electromagnetic rotary sensor for reliable digital position tracking (Series 340).
