Mitutoyo 543-717B Electronic Drop Indicator 0.5 in

Product Description

The MITUTOYO 543-717B is an electronic drop indicator designed for precision dimensional measurement in manufacturing, machining, and quality control environments. The indicator features an LCD display with a resolution of 0.0005 inch and an accuracy of plus or minus 0.001 inch, making it suitable for tight-tolerance inspection work. A carbide contact point provides long service life under repeated use. The integrated analog bar gives technicians a fast visual reference for deviation without requiring them to read the numeric display directly. Licensed metrologists, machinists, and quality technicians are the primary users.

The MITUTOYO 543-717B is suited for bench inspection setups, surface plate work, and in-line measurement stations where drop-style indicators are required. The flat back accommodates standard indicator holders and magnetic base arms. The straight connection type allows direct mounting to common indicator stands. The unit supports both inch and metric measurement modes, covering a range from 0 to 0.5000 inch (0 to 12.70 mm). A built-in data output port enables integration into measurement networking and statistical process control (SPC) systems, making it appropriate for production-floor quality programs.

Key Features

• LCD display with 0.0005 inch resolution for high-precision readings
• Accuracy of plus or minus 0.001 inch across the full measurement range
• Analog bar display integrated for quick deviation reference at a glance
• Tolerance judgment function with user-settable upper and lower limits
• Data output port supports SPC system integration and measurement networking
• Carbide contact point for extended wear resistance in repeated-use applications
• Operates on included CR2032 battery; switches between inch and metric modes

Compatibility

Designed as an OEM-style electronic drop indicator compatible with standard flat-back indicator holders, magnetic base arms, and indicator stands accepting a straight connection type.

Installation Notes

Installation is performed by machinists, metrologists, or quality technicians using standard indicator holders or magnetic base assemblies. Secure the indicator firmly in the holder before zeroing to prevent measurement error from movement. Verify contact point engagement angle and measuring force direction are consistent with the application before recording readings. Do not exceed the stated measuring force or measuring range during use.
