Spi 29-005-6 Electronic Drop Indicator 0 to 0.5 Inch

Product Description

The SPI 29-005-6 is an electronic drop indicator designed for precise dimensional measurement in trade and industrial applications. It covers a measurement range of 0 to 0.5 inches with a resolution and accuracy of 0.0005 inches, making it suitable for surface plate work, machine setup, and tolerance verification tasks. The electronic readout eliminates the analog dial, reducing reading errors during repetitive inspection cycles. Machinists, toolmakers, metrology technicians, and precision-trade professionals use this indicator where consistent, repeatable linear measurement is required.

The 29-005-6 is suited for use in machine shops, fabrication environments, and quality control stations. It fits standard drop indicator holders and magnetic base setups commonly used for runout checks, flatness verification, and part alignment on mills, lathes, and surface plates. The compact body size of 4.5 inches by 2.5 inches by 1.8 inches allows use in confined fixture setups. This unit ships as a single piece and is appropriate for both bench-level inspection work and production-floor measurement tasks.

Key Features

• Measurement range of 0 to 0.5 inches for short-travel dimensional checks
• Resolution of 0.0005 inches for fine-tolerance work
• Accuracy of 0.0005 inches across the full range
• Electronic readout for clear, direct digital display without dial interpolation
• Compact footprint at 4.5 x 2.5 x 1.8 inches for use in tight setups
• Lightweight at 0.5 pounds for easy positioning and handling

Compatibility

Designed as a standard electronic drop indicator compatible with conventional drop indicator holders and magnetic base mounting systems used in general metrology and machining applications.

Installation Notes

Installation and use of this indicator is typically performed by machinists, toolmakers, or metrology technicians. Secure the indicator firmly in a drop indicator holder or magnetic base before zeroing the display to avoid measurement errors from movement or vibration. Do not exceed the rated measurement range of 0.5 inches, as overtravel can damage the internal sensing mechanism. Handle the contact point and spindle with care to maintain calibration accuracy.
