Mitutoyo 227-217-20 ABSOLUTE Digital Adjustable Measuring Force Micrometer, .8′′ – 1.2′′ (20.32 - 30.48 mm)

Part Number: Mitutoyo 227-217-20

The Mitutoyo 227-217-20 adjustable force micrometer lets you set the measuring force in stages of 2, 4, 6, 8, or 10 N, helping measure soft and thin parts without squeezing them out of shape. It covers 0.8"–1.2" (20.32–30.48 mm) with an ABSOLUTE digital display and a fast 10 mm-per-turn spindle.

A standard micrometer applies a fixed force that works well for hardened steel but can distort parts that deform under measurement pressure. The Mitutoyo 227-217-20 solves this by allowing the operator to select a controlled measuring force, helping maintain consistent measurement conditions between operators.

The spindle does not rotate, so the measuring faces meet the part without twisting or scuffing it. With 10 mm feed per revolution, it provides fast spindle travel for efficient measurement. The ABSOLUTE encoder provides 0.00005" / 0.001 mm resolution with Inch/Metric switching.

Typical applications include plastic mouldings, gaskets, springs, thin-wall tubing, coated components, polymer parts, and elastomer components. It is suitable for machine shops, QC inspection, incoming inspection, maintenance work, and applications where controlled measuring force is important.

For the best results, allow the Mitutoyo 227-217-20 and the workpiece to reach the same temperature before precision measurement. Temperature differences can affect dimensional readings, particularly when moving parts between hot workshop areas and cooled inspection rooms.

For a smaller range at the same force, the Mitutoyo 227-216-20 covers 0.4"–0.8". For very soft parts requiring a lower 0.5–2.5 N force range, consider the Mitutoyo 227-211-20.

Key Benefits

• No part distortion — controlled measuring pressure helps keep soft and thin parts in shape.

• Fast spindle — 10 mm per revolution speeds up setup between different sizes.

• Non-rotating spindle — measuring faces meet the part without twisting or scuffing.

• ABSOLUTE digital display — 0.001 mm resolution with no re-zeroing at power-on.

• Long battery life — approximately 5 years under normal use.

• Controlled measuring force — select from 2, 4, 6, 8, or 10 N according to the material and application.

Who This Product Is Best For

• QC teams inspecting plastic mouldings and other compliant parts.

• Polymer, rubber, and packaging manufacturers checking thickness and diameter.

• Maintenance workshops measuring seals and gaskets before fitting.

• Laboratories requiring consistent measuring force between operators.

• Buyers moving from conventional ratchet-thimble micrometers to controlled-force measurement.

How to Use

1. Select the measuring-force stage that suits the material and application.

2. Check the zero using the reference or supplied setting standard.

3. Position the measuring faces on the part.

4. Close the spindle onto the part so the preset measuring force is applied consistently.

5. Read the measurement on the digital display or transfer the value to a compatible data-logging system.

Frequently Asked Questions

What range does the Mitutoyo 227-217-20 adjustable force micrometer cover?

It measures 0.8"–1.2" (20.32–30.48 mm) and supports Inch/Metric switching.

What measuring force settings are available?

The measuring force is adjustable in stages of 2, 4, 6, 8, and 10 N. The force tolerance is ±0.4 N + (force setting ÷ 10).

Why use an adjustable force micrometer?

Soft or thin parts can compress under the force of a conventional micrometer and produce undersized readings. Adjustable measuring force helps apply controlled pressure and improve repeatability between operators.

Does the spindle rotate?

No. The spindle is non-rotating and provides 10 mm feed per revolution, allowing the measuring faces to contact the part without twisting against it.

Which model should I choose if my part is outside 0.8"–1.2"?

Choose the model according to the required measurement range and measuring force. The Mitutoyo 227-216-20 covers 0.4"–0.8" with the same force group, while the Mitutoyo 227-211-20 is designed for the lower 0.5–2.5 N force range.

Can it be recalibrated?

Yes. The Mitutoyo 227-217-20 can be periodically recalibrated through an ISO/IEC 17025-accredited calibration service to maintain measurement traceability.
