Mitutoyo 227 Digimatic Micrometers

Digimatic micrometer equipped with a constant/low measuring force mechanism. The measurement-value hold function automatically retains the data at a specified measuring force. (Pressing with a larger force than the specified measuring force does not affect the measurement result.)
It is suitable for measuring flexible workpieces such as electric wire, paper, and rubber.
Non-rotating spindle reduces workpiece deformation.
Measuring faces: Carbide tipped

Measurement posture: horizontal orientation only (Recommended spindle inclination: within ±3°)
Power source: SR44 battery (1 pc.), 938882 included as standard (for operational checks)
Battery life: Approx. 5 years under normal use
Position detection method: Electrostatic capacity absolute sensor
Standard accessories: Setting standard, 1 pc. (except for measuring range 0 to 15mm (0 to 0.6 in)/0 to 10 mm (0 to 0.4 in) models), Screwdriver (210183), 1 pc.
These values are guaranteed when micrometer is used in a horizontal orientation (within ±3 degrees)

Adjustable Measuring Micrometers

Measuring force is generated by the action of trapping a workpiece between the spindle face and the anvil.
The constant-force unit applies the specified measuring force.
When the preset measuring force is reached, the count on the LCD is automatically held and the hold symbol appears.

(To cancel the hold, reverse the thimble more than 1/10 revolution and press the hold button.)
