Mitutoyo 543-732B Electronic Test Indicator

Product Description

The MITUTOYO 543-732B is a digital electronic test indicator designed for high-precision dimensional measurement in machining, inspection, and quality control environments. It features a carbide contact point that resists wear during repeated use on hard workpiece surfaces. The instrument delivers a resolution of 0.001 mm and an accuracy of 0.005 mm, making it suitable for surface runout checks, bore alignment, and comparative gauging tasks. Licensed machinists, tool and die makers, metrology technicians, and CNC setup personnel are the primary users of this class of instrument.

The 543-732B is applied in machine shop and quality lab settings where fine surface variation must be captured digitally. It is well suited for checking part flatness, runout, and concentricity on mills, surface plates, and inspection fixtures. The measurement range runs from 0 to 50.80 mm, covering the span needed for most comparative inspection applications. The digital output simplifies reading and reduces observer error compared to analog dial indicators.

Key Features

• Resolution of 0.001 mm for fine measurement discrimination
• Accuracy rated at 0.005 mm
• Carbide contact point for extended wear resistance on hard surfaces
• Measurement range from 0 to 50.80 mm
• Digital electronic display eliminates parallax reading error

Compatibility

Designed as an OEM-style electronic test indicator for use with standard indicator holders, magnetic bases, and inspection fixtures that accept this class of gauge instrument.

Installation Notes

Metrology technicians and machinist-level personnel typically mount and set up electronic test indicators. Secure the indicator in a rigid holder or magnetic base before zeroing the instrument to prevent false readings from vibration or flex. Avoid lateral overload beyond the stated travel range, as this can damage the sensing mechanism. Handle the carbide contact point carefully during stylus changes to protect the measurement stem.
