When your calibration work depends on accurate surface roughness readings, the stylus you choose matters. The Mitutoyo 12AAC731 roughness measurement standard stylus is available as a single unit at USD 233.89, and the main question is whether this 2um stylus fits your existing setup and your measurement needs.
Quick Verdict
The Mitutoyo 12AAC731 is a roughness measurement standard stylus listed in new condition with original packaging, priced at USD 233.89. It's a focused, no-frills option for technicians who already work with this part number and need a replacement or spare. The listing doesn't include compatibility details, so you'll want to confirm it matches your gauge before purchasing.
Who It Suits
This stylus is suited for calibration labs, quality inspection stations, or field technicians who use roughness testers compatible with the 12AAC731 stylus. Because the listing doesn't list adapters or compatible models, it's best for someone who already knows this is the right part. It's also a reasonable candidate if you need a standard stylus with a 2um spec and are willing to check fit yourself.
What Stands Out from the Listed Details
The item description emphasizes that it's a new part with original packing, and the condition attribute confirms new. The '2um' in the title is a key detail, giving you a specific stylus characteristic upfront. No extra accessories or calibration certificates are mentioned, so what you see in the listing is the stylus itself.
Mitutoyo 12AAC731 Roughness Measurement Standard Stylus 2um
This listing offers the Mitutoyo 12AAC731 as a compact roughness measurement standard stylus. The 2um designation is the most concrete spec in the title, making it easy to compare with your test requirements. One clear limitation is that the listing doesn't provide compatibility or installation instructions, so you must rely on your existing knowledge or match it to your equipment.
Meaningful Trade-offs
The biggest trade-off is that the listing doesn't say which roughness testers this stylus fits. With no compatibility list or dimensions, you need to rely on your own knowledge of the 12AAC731 part number. The stylus is also offered on its own, with no case or wrench included, according to the listing.
Bottom Line
If your equipment calls for the Mitutoyo 12AAC731 and you're comfortable with the USD 233.89 price for a new, original-packed stylus, this is a straightforward option. It's not a bundle and it doesn't come with extra guidance, so it's best for buyers who know exactly what they need.
