Mitutoyo 340-252-30 Digital Micrometer With Interchangeable Anvils, Range 150-300mm

The Mitutoyo 340-252-30 is a Series 340 digital outside micrometer with interchangeable anvils and a 150-300 mm measuring range, designed for accurate measurement of large shafts, housings and other machined components. Its interchangeable-anvil design allows one frame to cover multiple measuring ranges, while the digital display provides clear readings for large-dimension inspection. Genuine Mitutoyo from General Tech, authorised distributor in Saudi Arabia.

Large components often require multiple micrometer ranges, making separate frames expensive to purchase and difficult to store. The Mitutoyo 340-252-30 addresses this with interchangeable anvils that allow a single frame to cover a 150-300 mm measuring range. A ratchet stop provides consistent measuring force, while supplied zero-setting standard bars help establish the correct origin for each anvil range. The digital readout makes measurements easier to read on large components and helps reduce reading errors associated with traditional mechanical micrometers. It is well suited to heavy engineering, machining and inspection applications where large diameters need to be measured accurately.

For reliable results, allow the micrometer and workpiece to reach the same temperature before measurement and avoid holding the frame for extended periods, as hand heat can affect large-frame measurements. Before ordering, confirm the required measuring range and anvil configuration. General Tech can also assist with calibration requirements.

Frequently Asked Questions

How does the interchangeable-anvil micrometer work?
The interchangeable anvils change the effective measuring range of the frame, allowing one micrometer to cover multiple large measurement ranges.

What is the measuring range of the Mitutoyo 340-252-30?
The measuring range is 150-300 mm.

Does it have interchangeable anvils?
Yes. The 340-252-30 uses interchangeable anvils to provide a wider measurement capability from one frame.

Does it have a digital display?
Yes. The Mitutoyo 340-252-30 is a digital outside micrometer with a clear digital readout.

Does it use a constant-force device?
Yes. A ratchet stop helps provide consistent measuring force during measurement.

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

Should I choose the 340-252-30 or 340-351-30?
The 340-252-30 covers 150-300 mm, while the 340-351-30 covers 0-6". Choose the model based on the dimensions of the components you need to measure.

How should I care for the micrometer?
Clean the measuring faces and anvils after use and store the instrument in its case away from heat, humidity and coolant. Regular calibration is recommended for precision inspection work.
