Mitutoyo 500-173-30 Absolute Caliper 0-12"/ 300mm SPC

The Mitutoyo 500-173-30 is a 300 mm (12-inch) Absolute Digimatic caliper with SPC data output, built with hardened stainless steel construction and carbide-tipped jaws. This is the largest standard Digimatic caliper in the 500 series — ideal for measuring larger workpieces, extrusions, flanges, and structural components that exceed the range of 150 mm and 200 mm models.

Powered by Mitutoyo's Absolute (ABS) electromagnetic induction scale, the 500-173-30 requires no origin reset after power-on — simply open the jaws and start measuring. The ABS encoder is immune to coolant, oil, and swarf contamination on the scale face, and the high-contrast LCD with 9 mm character height is easy to read even in low-light shop environments. With 0.01 mm resolution and SPC output, this caliper bridges the gap between manual measurement and digital quality documentation.

✦ Key Features

300 mm / 12" Measuring Range — Covers larger workpieces that 150 mm and 200 mm calipers cannot reach, with the same Digimatic precision.

Absolute (ABS) Scale — No origin reset required after power-on. The electromagnetic induction encoder remembers its position, so you never lose zero.

Carbide-Tipped Jaws — OD measuring faces are carbide-tipped for extended wear resistance when measuring hardened steel, cast iron, and abrasive materials.

SPC Data Output — Digimatic output port connects to data processors, USB interfaces, and SPC software for paperless inspection and process control.

Contamination-Resistant Scale — The ABS encoder is unaffected by water, oil, or chips on the scale surface — reliable readings even in wet machining environments.

High-Contrast LCD — 9 mm character height with crisp digits, readable at a glance under any lighting conditions.

Frequently Asked Questions

What does "Absolute" mean on this caliper?
The Absolute (ABS) scale uses electromagnetic induction to track position — it never loses its origin, even after power-off. You don't need to close the jaws and reset zero when you turn it on, unlike older incremental digital calipers.

Are the jaws carbide-tipped?
Yes — the outside measuring faces are carbide-tipped for wear resistance. The inside jaw faces are hardened stainless steel.

Can I connect this caliper to a computer?
Yes. The SPC Digimatic output connects to Mitutoyo USB Input Tools or wireless data transmitters for direct data transfer to Excel, SPC software, or quality management systems.

How long does the battery last?
The SR44 battery lasts approximately 3.5 years (20,000 hours) under normal use — one of the longest battery lives in any digital caliper.
