🔍 What to Confirm
When buying, make sure:
-
The graduation (least count) is truly 0.001mm. Some indicators are 0.01mm, which is one order of magnitude less precise.
-
The range is sufficient — you asked for ~0.14mm; the 513â401â10H gives exactly that.
-
Verify the type/contact stylus (ruby tip vs carbide etc.), that may affect sensitivity & durability.
-
The measuring force and lever mechanism — lower force usually gives less deformation on delicate parts.
-
That your supplier is authentic Mitutoyo or an authorized dealer, to avoid counterfeits.
⚙ïļ Other Options / Alternatives
If the exact 0â0.14mm / 0.001mm spec is hard to get, you might consider:
-
Indicators with slightly higher range or slightly different format if your application allows.
-
Digital indicators of similar resolution if you want easier reading, though sometimes at cost or complexity.
-
Renting or borrowing for occasional use, if high precision is needed only rarely.
✅ Recommendation
Of the two listed above, the Mitutoyo 513â401â10H is the best match to your spec (0â0.14 mm, 0.001 mm). If you're okay with paying the price, that looks like a solid buy. If you like, I can check several dealers in Pattaya for stock & price for that exact model. Do you want me to do that?
