Description
Product Overview
When you need to plug an indicator into a height stand, a bore gauge, or a custom fixture and get real micron-level readings — not just a dial you have to squint at — a digital plunger indicator is the only sensible answer. The Mitutoyo 543-390B is the workhorse of the ID-C line: a compact ABSOLUTE Digimatic indicator with 0.001mm resolution, 12.7mm travel, and a large LCD that’s readable from across the bench. ABSOLUTE encoder technology means it never loses origin — switch it on and it already knows where zero is, a huge step up from incremental digital indicators that need re-zeroing every power-cycle. This one is second-hand but fully functional and reading accurately.
- 0.001mm resolution with ±3μm accuracy — genuine micron-level measurement in a compact digital housing.
- 12.7mm measuring range — plenty of travel for bore gauge duty, height stands, comparator setups, and general inspection work.
- ABSOLUTE (ABS) linear encoder — the indicator retains its origin through power-off and battery changes. No re-zeroing, no drift.
- GO/±NG tolerance judgement — set upper and lower limits for pass/fail inspection work.
- SPC data output port for connecting to Mitutoyo Digimatic data collectors, QC software, or statistical process control systems.
- Standard 8mm stem — fits every common indicator holder, bore gauge body, and height stand on the market.
- Ideal for use in bore gauges (Mitutoyo 511 series, etc.), height stands, comparator setups, fixture gauging, and SPC-driven QC work.
Condition
Used (Good Working Condition / No Box).
Straight talk on this one: this 543-390B has seen previous service. Cosmetically expect some shop patina — light handling marks on the body and bezel consistent with genuine use rather than a tool pulled out of a display case. Mechanically it’s been tested and is in full working order: the spindle moves smoothly through its full 12.7mm travel with no sticking, the LCD is clear with no missing segments, all buttons respond correctly, and readings check out accurately against a reference. ABS origin holds through power-cycling as it should. No box, paperwork, or fitted case is supplied — you’ll get just the bare indicator. A reliable digital indicator for shop use at a fraction of the cost of a new unit. As always with used measuring gear, we recommend a verification pass against your own standards before production use.
Included:
- 1 x Mitutoyo 543-390B Digimatic Indicator (ID-C112XB)

Brand Information
Mitutoyo is the global benchmark in precision metrology — founded in Tokyo in 1934 and the default specification on virtually every engineering drawing worldwide. The ID-C series of digital indicators is a mainstay of Japanese QC and toolroom work, renowned for long-term reliability, stable ABS encoder performance, and battery life measured in years rather than months. Even second-hand, a Mitutoyo digital indicator outperforms most new budget units on the market.
