Choosing a digital caliper for dimensional metrology machine inspection usually comes down to two questions: how large are the parts you measure, and do you need to send those readings somewhere? Mitutoyo offers two Absolute Digimatic models with noticeably different price tags: the 500-196-30 at USD 46.72 and the 500-172-30 at USD 153.30. This head-to-head compares their measuring range, output capability, and the price gap between them so you can decide quickly.
Quick verdict
If your inspection work fits inside the shorter range and you record readings by hand, the 500-196-30 is the practical pick. It gives you the core functions of a digital caliper at a much lower listed price. If you need more reach or want to capture measurements electronically, the 500-172-30 is worth the larger outlay. The real decision is whether output and extra measuring capacity justify the price gap between them. For many small-part inspection routines, the lower-priced model will do; for larger components or documented measurements, the output-equipped model earns its higher listing.

Where each product wins
The 500-196-30 wins on price and simplicity, with a straightforward digital readout that suits everyday checks. The 500-172-30 wins on measuring reach and the additional functions bundled into its data-equipped design. If you only need occasional readings, the simpler model keeps more money in your pocket; if the job calls for longer parts or recorded measurements, the data-equipped model has the edge.
Mitutoyo 500-196-30 0-6\" 150mm Absolute Digimatic Vernier Caliper Japan
For shop-floor checks that stay within 6 inches, this caliper is the lower-cost entry into Mitutoyo's Absolute Digimatic line. It reads in 0.0005-inch steps and is built for four-way measurement: outside, inside, depth, and step, which covers most quick inspection tasks without any extra hardware. The trade-off is data output: the listing shows no SPC output, so any reading you want to save has to be recorded manually. If your procedures require electronic capture, this model will slow you down. It also cannot measure past its 6-inch maximum, so longer parts need a separate tool. For a machinist who mostly checks smaller features and wants a dependable digital caliper without paying for output, this is the one to start with.
MITUTOYO Digital Caliper, 500-172-30 8\"/200MM AOS ABS with Output
The extra money on this 8-inch model buys two things: more measuring reach and output capability. The AOS ABS designation and the included output function are the defining features, which is useful when you need to document measurements during machine inspection. The limitation is the listed amount: it carries a price gap of roughly USD 106 above the 6-inch model, so it only makes sense if you will actually use the larger range or the data connection. If your parts are all under 6 inches and you are comfortable with manual recording, the higher-priced model is more than you need. But for shops that inspect larger components or need to log readings, the 8-inch output-equipped caliper is the more complete tool.
Final choice by use case
- For typical smaller work without data logging: choose the 500-196-30. It handles routine checks at a much lower listed price.
- For larger work or data-capture needs: choose the 500-172-30. The extra measuring range and the ability to document measurements directly justify the higher listing where that workflow matters.
