Mitutoyo 543-597B-10 Electronic Drop Indicator 2 in

Product Description

The MITUTOYO 543-597B-10 is an electronic drop indicator designed for dimensional measurement in precision metrology and quality-control applications. It features an LCD display with a resolution of 0.00005 inch (0.0005 mm) and an accuracy of 0.003 mm, making it suitable for high-precision surface, runout, and concentricity checks. The measuring range spans from 0 to 2 inches (0 to 50.80 mm). The indicator uses a flat back and a straight connection type, and is powered by an included silver oxide battery. It is installed and used by machinists, quality technicians, and tool-and-die professionals on surface plates, magnetic bases, and precision fixtures.

This drop indicator is suited for use in machine shops, manufacturing facilities, and inspection departments requiring reliable electronic measurement. Its straight connection and flat back make it compatible with standard AGD Group 2 indicator holders and magnetic base setups. The measuring force ranges from 0 to 2.3 N, keeping contact pressure low enough to protect delicate workpiece surfaces. Typical applications include checking shaft runout, verifying flatness, and inspecting part-to-part dimensional variation during production or incoming inspection.

Compatibility

Designed as an AGD Group 2 electronic drop indicator compatible with standard AGD-style indicator holders, magnetic bases, and surface plate fixtures commonly used in precision inspection setups.

Installation Notes

Installation is performed by machinists or quality technicians familiar with precision measurement equipment. Mount the indicator securely in an AGD-compatible holder or magnetic base, ensuring the contact point is perpendicular to the measured surface to avoid cosine error. Do not exceed the specified measuring force range when seating the contact point against the workpiece. Handle the contact point and spindle with care to avoid damage that could affect calibration and accuracy.
