What is the measuring range of this outside micrometer?

This outside micrometer measures dimensions from 25 to 50 mm.

What is the graduation accuracy of this tool?

The vernier scale allows precise readings down to 0.001 mm.

What is the advantage of the ratchet thimble mechanism?

The ratchet operates from both the thimble and speeder for easy one-handed use at a constant measuring force.

Is a setting standard included with this model?

Yes, this 25 to 50 mm model comes standard with a 25 mm setting bar.

How does the frame minimize thermal expansion?

The frame features heat insulation to prevent body heat transfer from affecting measurements.

Accurate outside measurements with Mitutoyo

Practical benefits

Effortless one-handed operation: The integrated ratchet thimble allows you to smoothly position and adjust the spindle with one hand.
Constant preset measuring force: The ratchet mechanism ensures uniform contact pressure, delivering highly repeatable and reliable measurement readings.
Durable carbide measuring faces: Wear-resistant carbide tips protect the contact surfaces against abrasion to maintain precision over long periods.

In a nutshell

The right choise for

With the Mitutoyo 102-708 outside micrometer, you achieve reliable external measurements from 25 to 50 mm. Its vernier scale enables precise readings down to 0.001 mm, making it an essential tool for cnc machining, metalworking, and rigorous quality inspection. The dual-action ratchet thimble works from both the thimble and the speeder, providing smooth one-handed operation and a constant measuring force for consistent repeatability. Durable carbide-tipped measuring faces protect against wear, while the heat-insulated frame prevents body heat transfer from compromising measurement accuracy. Use the included 25 mm setting standard to quickly verify zero alignment and start measuring with complete confidence.
