Mitutoyo Digital Indicator Gauge 543-561-1

Description

Product Overview

When you’re checking runout on a shaft, verifying flatness across a surface plate, or tramming a mill head down to the last thou, the last thing you need is an indicator that drifts, resets poorly, or forces you to squint at a needle through worn graduations. A reliable digital indicator with genuine zero-setting capability and crisp resolution is the difference between chasing your tail and getting the job done in one setup. The Mitutoyo 543-561-1 ID-C Series digital dial gauge delivers exactly that — a full 30.4mm measuring range with 0.001 mm resolution, a large LCD readout, and Mitutoyo’s trusted linear encoder mechanism in a robust, shop-proven body. This unit is in great condition and includes the power supply, making it ready to bolt into your indicator stand and get to work immediately.

• 0.0005 mm (1/2 micron) resolution with ±0.0015 accuracy — For runout checks, bore alignment, and surface parallelism work where analogue gauges leave you interpolating between graduations, this resolution level gives you a definitive, repeatable number every time.
• 30.4mm (1.2″) measuring range — Enough stroke to handle the full range of practical indicator setups without constant re-positioning, from checking lathe chuck jaw alignment to verifying flatness across a milled face.
• Large LCD with SET/ZERO, MODE, and DATA/Fn controls — The SET/ZERO function lets you null the gauge at any point in the travel instantly, critical when you’re working relative measurements on the fly. The DATA output function supports SPC/data logging when connected to a Mitutoyo data interface — useful in a production or inspection environment.
• Standard 8 mm stem (shank) — Fits the vast majority of Australian workshop indicator holders, back-plunger stands, magnetic bases, and surface gauge stems without adapters. Compatible with Mitutoyo, Kanetop, and generic 8 mm clamp-style holders.
• Ideal for tramming mill heads and vices, four-jaw independent chuck setup, lathe bed levelling, surface grinder table parallelism, runout checks on turned components, CMM probe substitution in manual inspection fixtures, and toolroom final inspection work.

Condition

Used (Good Condition / Shop-Used, Fully Functional)

The gauge presents well for a used instrument. The body is in good condition with no cracks, chips, or damage to the housing that would affect use or mounting. The LCD is clear and fully legible, and all three buttons — MODE, SET/ZERO, and DATA/Fn — are functional. The spindle moves freely through its full travel without binding and has a dampener to slow its return. The contact point and stem shows no wear.
A new power supply is included, which means the unit is ready to operate straight out of the box. As with any used precision instrument, it is recommended practice to verify the gauge against a known reference — a calibrated slip gauge stack or toolroom-grade ground reference surface — before committing it to critical inspection work. This is good workshop hygiene regardless of how new the tool is.

Included:

• 1 x Mitutoyo 543-561-1 ID-C Series Digital Dial Gauge (0–30.4mm / 0.0005 mm resolution)
• 1 x New Power supply

Not included: Original carry case, setting ring, spare contact points, data cable or SPC interface unit.

Brand Information

Mitutoyo Corporation, founded in Japan in 1934, is the global benchmark in precision metrology instrumentation — their name sits at the top of the same tier as Mahr, Tesa, and Starrett when toolmakers and metrologists are discussing instruments they’ll stake a tolerance on. Manufactured in Japan to ISO and JIS standards, Mitutoyo gauges are specified by aerospace, automotive, defence, and precision engineering firms worldwide precisely because their calibration traceability, build quality, and long-term repeatability are consistently proven in production and toolroom environments. Buying a used Mitutoyo is a fundamentally different proposition to buying a used generic instrument — the underlying engineering holds up over years of shop-floor service in a way that cheaper alternatives simply don’t.
