Mitutoyo 340-351-30 Digital Micrometer With Anvils, Range 0 To 6"

The Mitutoyo 340-351-30 is a Series 340 digital outside micrometer with interchangeable anvils and a wide 0-6" measuring range. Designed for large components, it allows multiple measuring ranges to be covered using a single frame by changing the interchangeable anvils. A ratchet stop provides consistent measuring force, while the digital display makes readings easier to record accurately on large machined parts.

The interchangeable-anvil design makes the Mitutoyo 340-351-30 practical for heavy engineering and inspection applications where component sizes vary. Zero-setting standard bars are supplied to establish the correct origin for each anvil range. The digital readout helps reduce reading errors associated with large mechanical micrometers. For accurate results, allow the micrometer and workpiece to reach the same temperature before measuring and avoid holding the frame for extended periods.

Frequently Asked Questions

How does an interchangeable-anvil micrometer work?
The measuring range is changed by replacing the interchangeable anvils, allowing one micrometer frame to cover multiple ranges.

What is the measuring range of the Mitutoyo 340-351-30?
The micrometer covers a 0-6" measuring range.

Are zero-setting standards supplied?
Yes. Zero-setting standard bars are supplied for accurately setting the micrometer for the applicable anvil range.

Does the micrometer have a constant-force device?
Yes. A ratchet stop helps provide consistent measuring force during measurement.

What is the Mitutoyo 340-351-30 used for?
It is suitable for measuring large shafts, housings, and other large machined components in heavy engineering and inspection applications.

Should I choose the 340-351-30 or the 340-252-30?
The 340-252-30 covers 150-300 mm, while the 340-351-30 provides a 0-6" range with interchangeable anvils. Match the measuring range and configuration to your application.

How should I care for the instrument?
Wipe the measuring faces and anvils clean after use and store the micrometer in its case away from excessive heat, humidity, and coolant. Regular calibration helps maintain measurement accuracy.

Can the Mitutoyo 340-351-30 be calibrated?
Yes. General Tech Saudi provides calibration services for dimensional measuring instruments. Contact the team when ordering if calibration is required.

Can you supply other Mitutoyo instruments?
Yes. General Tech supplies a wide range of Mitutoyo micrometers, bore gauges, calipers, indicators, and other precision measuring instruments.

Is genuine Mitutoyo available in Saudi Arabia?
Yes. General Tech is an authorised Mitutoyo distributor in Saudi Arabia.
