Choosing a digital caliper for machine inspection usually comes down to three things: how long your parts are, whether you need data output for documentation, and how much you want to spend. All four calipers here carry the Absolute Digimatic name, so you are looking at direct-reading digital tools rather than dial or vernier calipers. The differences show up in maximum measurement, price, and extras such as SPC output and the included case.
Quick take
If you regularly measure longer parts, the 500-193-30 is the one to start with. If a compact tool is enough, the 500-196-30 option is the lowest-priced in this group. If you want a middle ground, the 500-197-30 includes the original case and box.

Product notes
500-193-30 New Mitutoyo 300mm/12-Inch Absolute Digimatic Caliper
The longest model here, the 500-193-30, measures from 0 to 12 inches and has a data output port for SPC transfer, so it fits inspection work that needs documented readings. The description lists ±0.02 mm (±0.001-inch) accuracy, an Absolute encoder that skips origin resetting, a digital LCD, metric/inch conversion, and stainless-steel construction. At USD 89.10, it carries the highest listed price in this group. That price makes sense when your parts regularly exceed 8 inches or you need SPC connectivity; if your work stays small, you can save money with a 6-inch model.
Mitutoyo 500-196-30 150mm/6-Inch Absolute Digital Digimatic Caliper Japan
The compact 6-inch 500-196-30 is the price leader in this comparison at USD 45.00. It still gives you the Absolute Digimatic package: 0.0005-inch resolution, 0.01 mm/0.0005-inch/1/128-inch fractional display, instant metric/imperial conversion, zero/ABS function, and four-way measurements for outside, inside, depth, and step. The title also points to Japan as the country of origin. The limitation is data output: this model has no SPC output, so if you plan to send measurements straight to a computer or quality log, the 12-inch 500-193-30 is the better fit.
Mitutoyo Japan 500-197-30 0-200mm/8-Inch Absolute Digital Digimatic Caliper
The 500-197-30 splits the difference with a 0-200mm/0-8-inch range and a listed price of USD 55.80. It comes with the original case and box, which makes it easy to store between inspections. The title and description point to the same Absolute AOS Digimatic digital design, and the range covers work that is too long for a 6-inch jaw but shorter than a 12-inch tool. The limitation is reach: at 8 inches, it will not handle the longer parts the 12-inch model can measure. If all of your parts fit in 6 inches, the 6-inch models cost less.
150mm/0-6 Absolute Digital Digimatic Vernier Caliper Mitutoyo Japan 500-196-30
This option uses the same MPN as the 6-inch model but front-loads the metric range in the title: 150mm/0-6. It lists the same 0.0005-inch resolution, four-way measurement, dual-unit conversion, and zero/ABS function, and it identifies Japan as the country of origin. At USD 48.36, it costs more than the other 500-196-30 option while offering the same maximum measurement and resolution. It is a reasonable choice if you prefer this version of the product name or need a second 6-inch caliper, but the lower-priced 500-196-30 option delivers the same MPN for less.
Final recommendation
- Longest reach with SPC output: the 12-inch 500-193-30. It is the highest-priced item here, but it is the one that measures to 12 inches and includes a data output port.
- Everyday shop middle ground: the 8-inch 500-197-30. It brings the original case and box and costs less than the 12-inch model.
- Compact 6-inch price pick: the 6-inch 500-196-30. If you prefer the front-loaded 150mm/0-6 title, the alternate 500-196-30 option covers the same ground, but the lower-priced 6-inch option gives you the same model for less.
