金屬厚度測量儀 — 適用線材、板材與棒材，美規、公制與英制，0-30 範圍

The markings are crisp and easy to read, even on the smaller wire sizes. I've been using it to double-check my stock before pricing jobs, and it's already saved me from a costly mistake. Feels solid in the hand, too.

Finally, a gauge that actually tells me what I've got without guessing — the US Standard scale with decimal inches is spot-on for the non-ferrous sheet I use daily. The 0-30 range covers everything from thin wire up to chunky rod, and it's small enough to live in my bench drawer.

The numbered dial is crisp enough to read 30-gauge wire without squinting, and the circular design fits nicely in my palm while I sort scrap. Swapping between the US Standard and decimal scales on the same wheel saves me from digging out a conversion chart mid-project.
