Mitutoyo 543-707B Electronic Drop Indicator 0.5 in

Product Description

The MITUTOYO 543-707B is an electronic drop indicator designed for precision dimensional measurement in industrial and manufacturing environments. It features an LCD display with a resolution as fine as 0.00002 decimal inch and an accuracy of 0.0001 inch, making it suitable for high-tolerance inspection work. The integrated analog bar graph allows quick visual trend reading alongside the digital readout. Equipped with a data output port, the 543-707B supports connection to measurement networking and statistical process control (SPC) systems. It is powered by an included CR2032 battery and uses carbide contact points for durability under repeated use. Calibrated technicians, quality control inspectors, and precision machinists are the primary users of this instrument.

The 543-707B is used in machine shops, manufacturing cells, quality inspection stations, and tool rooms where tight dimensional tolerances must be verified. Its straight connection type and flat back make it compatible with standard indicator holders and magnetic base setups. The measuring range of 0.5000 inch (12.70 mm) suits a wide range of surface, runout, and comparative measurement tasks on machined parts. Tolerance judgment functionality is built in, allowing operators to set upper and lower limits for pass/fail inspection without additional software at the instrument level.

Key Features

• LCD display with selectable resolution: 0.00002, 0.00005, 0.0001, 0.0002, or 0.0005 decimal inch
• Integrated analog bar graph for real-time trend monitoring alongside digital readout
• Built-in tolerance judgment with user-settable upper and lower limits for pass/fail inspection
• Data output port for integration into SPC and measurement networking systems
• Carbide contact point for extended wear life in production environments
• Inch and metric unit display switchable on the instrument

Compatibility

Designed for use with standard drop indicator holders and magnetic base setups accepting a straight connection type and flat back mounting configuration.

Installation Notes

Mount the indicator securely in a compatible holder or magnetic base before zeroing the instrument. Power down or zero the display before repositioning the contact point to avoid false readings. Ensure the contact point is fully seated and the stem is clamped at the correct depth before recording measurements. Handle the contact point and spindle with care to avoid damaging the precision measuring surfaces.
