Mitutoyo 543-562A Electronic Drop Indicator 0-1.2 in

Product Description

The MITUTOYO 543-562A is an electronic drop indicator designed for precise dimensional measurement in industrial, toolroom, and quality-control applications. Part of the Mitutoyo 543 Series IDH Digimatic line, it measures from 0 to 1.2 inches (0 to 30.40 mm) with a resolution as fine as 0.00002 inches (0.00005 mm) and an accuracy of 0.0015 mm. The flat-back housing seats flush against a gauge stand or magnetic base, and the backlit LCD provides clear readings in both inch and metric units. A 9-volt battery is included. This indicator is used by machinists, quality technicians, and precision tradespeople who need reliable electronic gauging for surface, height, and runout checks.

The 543-562A fits standard 3/8-inch stem holders and magnetic base arms found on inspection fixtures, surface plates, and machine tool setups. It is well-suited for residential shop environments, production floors, and field calibration tasks where both inch and metric readout is required. The unit switches between inch and metric modes, making it compatible with mixed-unit workflows common in automotive, aerospace, and general manufacturing facilities. No specific model compatibility is listed by the manufacturer for this SKU beyond the IDH Series Digimatic Indicator designation.

Installation Notes

Seat the 3/8-inch stem securely in the holder clamp before zeroing the indicator; do not overtighten the clamp screw, as this can distort the stem and affect accuracy. Zero the display on a known reference surface before taking measurements. Handle the contact point and spindle with care to avoid impact that could affect calibration. Battery replacement should be performed with the unit powered off using a standard 9-volt battery.
