The Mitutoyo Series 227 Absolute Digimatic Micrometer is engineered with an integrated constant and low measuring force mechanism. Designed for precision metrology applications, the instrument features an automatic measurement-value hold function that retains data at a pre-specified measuring force, ensuring that additional applied force does not compromise measurement integrity. Equipped with a non-rotating spindle to minimize workpiece deformation and carbide-tipped measuring faces, this series is suited for measuring flexible materials such as electric wire, paper, and rubber.
- Constant/Low Measuring Force Mechanism: Applies a repeatable, adjustable measuring force via a measuring force control and stroke-limiting bush.
- Measurement-Value Hold Function: Automatically retains the LCD count when the preset measuring force is reached. (Hold can be cancelled by reversing the thimble more than 1/10 revolution and pressing the hold button).
- Non-Rotating Spindle: Reduces workpiece deformation during contact.
- Carbide-Tipped Measuring Faces: Provides enhanced durability and wear resistance.
- Built-In Functions: Adjustable measuring force mechanism, Origin point setting, Zero setting, Hold, Function Lock, Auto power off, Measurement data output, and Error display.
- Position Detection Method: Electrostatic capacity absolute sensor.
- Power Source: One (1) SR44 battery (Standard accessory 938882 included for operational checks).
- Battery Life: Approximately 5 years under normal use.
- Measurement Posture: Horizontal orientation only (Recommended spindle inclination: within ±3°).
