Choosing between two digital calipers for dimensional metrology machine inspection usually comes down to measuring range, data capture, and budget. The 0-6" model sells for USD 54.00, while the 8"/200mm model sells for USD 153.30-a spread that makes the lower-priced caliper 65% below the higher-priced one. Both are new, and both fit the same shop role, so the decision depends on how big your parts get and whether your inspection routine needs data capture.
Quick Verdict
For everyday inspection of smaller parts, the 500-196-30 is the sensible choice. It delivers a 0.0005 in resolution, hardened stainless steel construction, and a Zero/ABS button for comparative checks. None of those features adds complexity to the reading process, which is valuable when you are working through a stack of parts quickly. The 500-172-30 is the right call when parts are larger or when the reading needs to move beyond the display into a record-keeping step; it provides more travel for a larger spend.
Price and Range Comparison
| Product | Price | Price Bar | Measuring Range |
|---|---|---|---|
| New 500-196-30 Mitutoyo Digital Caliper | 0-6" (150mm) | Absolute Encoder US | USD 54.00 | 0-6" (150mm) | |
| MITUTOYO Digital Caliper, 500-172-30 8"/200MM AOS ABS with Output | USD 153.30 | 8" / 200mm |
Where Each Product Wins
500-196-30 wins on price and on everyday inspection of smaller components. The lower price leaves room in the tool budget, and the displayed resolution handles common checks.
500-172-30 wins when the part envelope is larger or when readings must be captured as part of a documented dimensional metrology machine inspection workflow. The extra travel is the main capability, and the model name calls out output.
Product Notes
New 500-196-30 Mitutoyo Digital Caliper \| 0-6" (150mm) \| Absolute Encoder US
This caliper's shorter span keeps it easy to use for routine checks. It has a 0.0005 in resolution, a Zero/ABS button for comparative readings, and hardened stainless steel construction. The scale uses an absolute electromagnetic linear encoder, so the tool can hold an absolute reference rather than relying on a floating zero each time. At the lower price point, it is the budget-conscious pick for parts that fit comfortably in hand and under the jaws. The limitation is the range: when your workpieces approach the full travel of the jaws, you will need a caliper with more capacity, and that is exactly what the other model in this pair provides.
MITUTOYO Digital Caliper, 500-172-30 8"/200MM AOS ABS with Output
This caliper's longer travel is its main advantage. The model name includes AOS ABS and with Output, so the tool is built for inspection tasks where the reading needs to move beyond the display into a record-keeping step. That becomes useful in dimensional metrology machine inspection when measurements need to be tied to a part or a process log. At the higher price point, the cost reflects the larger capacity and the additional function. For parts that do not fit under a shorter caliper, this model means fewer interruptions to swap tools. The limitation is the price: if the longer travel rarely gets used, the extra spending is hard to justify despite the output capability.
Final Choice by Use Case
- If your typical parts are small and you want a dependable caliper without stretching the budget, choose the 500-196-30.
- If your parts are larger or your process calls for data-ready measurements, choose the 500-172-30.
