Mitutoyo 543-700B Electronic Drop Indicator 12.70mm

Product Description

The MITUTOYO 543-700B is a metric electronic drop indicator designed for precise dimensional measurement in manufacturing, inspection, and machine setup applications. It delivers a measuring range of 0.00 to 12.70 mm with a resolution of 0.0010 mm and an accuracy of 0.0030 mm, making it suitable for tight-tolerance work. The indicator features an LCD display for easy reading and uses a flat back mounting style. A straight connection type and 8.000 mm stem diameter ensure compatibility with standard indicator holders and magnetic bases. The unit ships with a fitted plastic case and a SR44 silver oxide battery included.

This drop indicator is used in metrology and quality control environments where repeatable, high-resolution linear measurement is required. Typical applications include surface plate inspection, runout checks, and fixture setup on machining centers or grinding equipment. The flat back design suits bench-mount and arm-mount configurations common in production and inspection departments. The metric-only display and ISO-standard compliance make it appropriate for facilities operating under metric measurement protocols.

Key Features

Compatibility

Designed as a metric electronic drop indicator in the MITUTOYO 543 Series, compatible with standard 8.000 mm stem-diameter indicator holders and magnetic base arms used in general metrology and inspection setups.

Installation Notes

Installation is performed by metrology technicians or machinist-level personnel. Mount the 8.000 mm stem securely in a calibrated indicator holder or magnetic base arm before taking measurements. Ensure the contact point is perpendicular to the measured surface to avoid cosine error. Do not exceed the 1.50 N measuring force specification, as excessive contact force can affect accuracy and damage the mechanism.
