Mitutoyo 543-300-10 Electronic Drop Indicator Lcd

Product Description

The MITUTOYO 543-300-10 is an electronic drop indicator designed for precision dimensional measurement in manufacturing, machining, and quality control environments. It measures a range of 0 to 12.70 millimeters with an accuracy of 0.003 millimeters and a resolution of 0.001 decimal inch, making it suitable for tight-tolerance inspection work. The indicator features an LCD display for clear readout and runs on a CR2032 battery that is included. A flat back and straight connection type allow straightforward mounting in standard indicator holders and magnetic base setups. This tool is handled and installed by machinists, quality technicians, and metrology professionals.

The 543-300-10 is used in shop-floor and lab measurement applications where electronic readout is preferred over dial graduation. It is well suited for surface runout checks, bore alignment, and comparative measurement tasks on machine tools, surface plates, and fixture setups. Metric unit of measure is the default for this model. The measuring force is 1.5 newtons, which is light enough to protect delicate workpiece surfaces during contact measurement.

Key Features

• ABS (Absolute) scale restores the last origin position automatically when the indicator is powered on, maintaining measurement continuity
• LCD display provides a clear, direct digital readout in metric units
• Five dedicated buttons with status icons and clear labeling allow operation of a wide variety of functions
• Carbide contact point provides extended wear resistance under repeated use
• Flat back and straight connection type for compatibility with standard indicator mounting hardware
• CR2032 battery included; battery-powered with no external power supply required

Compatibility

Designed for use with standard indicator holders, magnetic bases, and test fixtures that accept drop-style electronic indicators with a straight shank connection and flat back mounting.

Installation Notes

Installation and setup should be performed by a qualified machinist or metrology technician familiar with indicator mounting procedures. Secure the indicator firmly in the holder or magnetic base before taking measurements to prevent movement that would affect accuracy. Avoid applying side loads to the spindle, as lateral force can damage the measuring mechanism. Zero the indicator or use the ABS recall function before beginning a measurement sequence.
