Mitutoyo 2802A-10 Dial Drop Indicator 0.0001 in Graduation

Product Description

The MITUTOYO 2802A-10 is a plunger-style dial drop indicator designed for precise dimensional measurement in machining, tooling, and inspection applications. It delivers a measurement range of 0 to 0.03 inches with a dial graduation of 0.0001 inches per division and an accuracy of plus or minus 0.0001 inches. The 0-10 dial reading and 0.01-inch range per revolution allow technicians to detect extremely fine surface variation or part deviation. A jeweled bearing mechanism provides consistent spindle movement and long service life under repeated use. The lug back mount supports standard clamp-on fixture setups. This indicator is suited for machinists, quality control technicians, tool and die makers, and precision metrology professionals.

The 2802A-10 is used in shop-floor and lab inspection environments where tight tolerances must be verified. Common applications include runout measurement, surface flatness checks, part alignment, and fixture setup on manual or CNC machine tools. The plunger-style indicator is appropriate for both horizontal and vertical measurement orientations. The lug back configuration allows secure mounting to magnetic bases, indicator holders, and clamp-on arms typically found in machine shop setups.

Key Features

• 0 to 0.03 inch measurement range with 0.0001 inch graduation for high-resolution readings
• Accuracy of plus or minus 0.0001 inches for repeatable, traceable measurement
• Jeweled bearing spindle for smooth, consistent travel and extended service life
• 0-10 dial face with 0.01 inch range per revolution for clear incremental reading
• Lug back with clamp-on base mount for compatibility with standard indicator holders and arms
• Plunger-style indicator body suited to both horizontal and vertical measurement setups

Compatibility

Designed as an OEM-style plunger dial indicator compatible with standard lug back clamp-on mounting systems used in precision metrology and machine shop inspection setups.

Installation Notes

Installation and use should be performed by a qualified machinist or metrology technician familiar with indicator mounting and calibration procedures. Secure the lug back to the clamp-on holder before bringing the spindle into contact with the measured surface to avoid overtravel damage. Always zero the dial face after mounting and before taking readings. Do not exceed the rated 0.03 inch measurement range, as spindle overtravel can damage the jeweled bearing mechanism.
