When you work in dimensional metrology machine inspection, the first tool decision is often about size: do you need a caliper that can span larger parts, or will a compact digital tool cover most of your checks? The two calipers here sit on opposite sides of that question. One is a Mitutoyo with a longer measuring span; the other is a stainless steel digital caliper with a much lower listed price. Both are listed as new.
Quick Verdict
If your inspection routine regularly involves larger parts, the MITUTOYO Digital Caliper, 500-172-30 8"/200MM AOS ABS with Output is the stronger pick. If most of your measuring stays within common shop sizes and you don't want to spend heavily just to get a dependable digital readout, the Stainless Steel Digital Caliper Vernier Micrometer Electronic Ruler Gauge Meter is the practical choice. The listed-price gap between them is about $131, so the decision comes down to how much extra measuring capability you'll actually use.

Product Notes
MITUTOYO Digital Caliper, 500-172-30 8"/200MM AOS ABS with Output
This is the longer-span option of the pair. It reaches 200mm, which makes it a better fit when parts in your dimensional metrology machine inspection routine are too big for a compact caliper. The AOS ABS with output feature adds flexibility when you need more than a simple readout. The clear trade-off is cost: it's the higher-priced model in this pair by a wide margin. If you mostly work with smaller parts and don't need extra output capability, you may be paying for reach you won't use. But when the job calls for that extra reach, this Mitutoyo has it covered.
Stainless Steel Digital Caliper Vernier Micrometer Electronic Ruler Gauge Meter
This stainless steel caliper covers the common 0-6"/150mm span and comes with a full-covered stainless steel body. The extra large LCD screen, inch/millimeter conversion, and auto-off feature are practical touches when you're moving between inspection tasks. The knurled thumb roller and locking screw help you position the jaws smoothly and hold a setting while you read the result. At $21.89, it's the lower-priced option in this comparison. The limitation is obvious: if a part needs the longer reach of the Mitutoyo, this one won't stretch that far. For smaller components and general shop measuring, it's the sensible grab.
Final Choice by Use Case
Choose the MITUTOYO Digital Caliper, 500-172-30 8"/200MM AOS ABS with Output when your inspection work regularly includes larger parts and you want the added capability that comes with this model. The higher cost is justified by that longer reach.
Choose the Stainless Steel Digital Caliper Vernier Micrometer Electronic Ruler Gauge Meter when most of your dimensional metrology machine inspection stays within compact part sizes. You get a stainless steel body, a large LCD, and flexible units at a far lower listed price.
