Starrett 49513 Electronic Drop Indicator 1 Inch Range

Product Description

The STARRETT 49513 is an electronic drop indicator with a 1-inch measurement range and an LCD display. It delivers an accuracy of 0.0001 inches (0.0020 mm), making it suitable for precision inspection, surface measurement, and quality control work in machine shops, fabrication environments, and maintenance settings. The 8.00 mm stem diameter fits standard indicator holders and magnetic bases. Two lithium CR2032 3V batteries are included, so the indicator is ready to use out of the box. Readings are available in both inch and metric units, which simplifies use across mixed-standard workflows. Machinists, tool and die makers, and maintenance technicians are the primary users of this instrument.

The STARRETT 49513 is used in applications where precise surface runout, height variation, or part deflection must be measured quickly and read clearly. The LCD readout eliminates the analog dial reading error common with mechanical indicators. It is well suited to bench inspection setups, machine tool maintenance, and fixture verification in both light industrial and precision manufacturing environments. The switchable inch and metric display allows a single instrument to serve multiple inspection requirements without recalibration.

Key Features

• 1-inch (25.00 mm) maximum measurement range covers most standard drop indicator applications
• Accuracy of 0.0001 inches (0.0020 mm) for high-precision surface and runout measurement
• LCD display provides clear, direct digital readout in inch or metric units
• 8.00 mm stem diameter fits standard indicator holders, magnetic bases, and transfer stands
• Includes two lithium CR2032 3V batteries for immediate use
• Switchable inch and metric modes on a single instrument

Compatibility

Designed for use with standard indicator holders and magnetic base stands that accept an 8.00 mm stem diameter, as commonly used in machine shop and industrial inspection setups.

Installation Notes

Mounting is performed by a machinist or quality technician using a compatible indicator holder or magnetic base stand. Ensure the stem is fully seated and the locking mechanism on the holder is snug before zeroing the instrument. Keep the indicator clear of cutting fluids and chips during use to protect the LCD and internal components. Battery replacement requires a small flathead screwdriver to open the compartment; use only the specified CR2032 3V lithium cells.
