Starrett 2700-805 Electronic Drop Indicator 0-4 in

Product Description

The STARRETT 2700-805 is an electronic drop indicator designed for high-precision dimensional measurement in industrial and trade applications. It covers a measurement range of 0 to 4 inches with a resolution of 0.000010 inches and an accuracy of 0.000200 inches, making it suitable for applications where tight tolerances are critical. The indicator features an LCD display and supports both inch and metric readout. It ships with a USB/AC power cable and compatible software for data output. Machinists, quality control technicians, and precision tradespeople install and operate this instrument on inspection fixtures, surface plates, and machine setups.

The 2700-805 is used in precision measurement tasks across manufacturing, machining, and toolroom environments. Its lug-on-center back mount allows it to seat securely in standard indicator holders and magnetic-base arms. The 3/8-inch stem diameter fits the majority of conventional drop indicator holders used in production and inspection settings. The dual inch and metric readout supports shops that work across both unit systems. Where accurate runout, flatness, or height measurements are required, this indicator provides a reliable electronic alternative to analog dial indicators.

Key Features

• Measurement range of 0 to 4 inches (0 to 100 mm) in a single instrument
• Resolution of 0.000010 inches (0.0020 mm) for fine-tolerance inspection work
• Accuracy rated at 0.000200 inches
• LCD display with selectable inch and metric readout
• Lug-on-center back mount for compatibility with standard indicator holders
• Includes USB/AC power cable and software for data capture and output

Compatibility

Designed for use with standard indicator holders and magnetic bases that accept a 3/8-inch stem diameter drop indicator. Verify holder clamping range and lug-on-center back clearance before installation.

Installation Notes

Mount the indicator in a suitable holder or magnetic-base arm before powering the unit. Ensure the stem is clamped securely without applying lateral force that could affect measurement accuracy. Connect the included USB/AC power cable to a stable power source or data-collection computer as needed. Calibration and zeroing should be performed with the indicator in its final mounted position prior to taking measurements.
