Tesa Brown Sharpe 00880403 Inside Micrometer 0.7-0.8 in

Product Description

The TESA BROWN SHARPE 00880403 is a mechanical inside micrometer designed for precision internal bore measurement in the 0.7000 to 0.8000 inch range. Featuring a 0.0002 inch graduation and a ratchet stop thimble, this instrument delivers consistent, repeatable readings with controlled measuring force. The three-contact-point design seats firmly in bores for stable contact and accurate positioning. Measuring faces are hardened steel, and the body carries a satin chrome finish for corrosion resistance and long service life. It is used by machinists, quality control inspectors, and precision tool technicians in shop and field measurement applications.

This inside micrometer is suited for precision bore and internal diameter measurement tasks in manufacturing, tooling, and metrology environments. The instrument supports measuring depths up to 3 inches in its standard configuration and up to 9 inches with one extension rod, making it adaptable across a range of internal measurement scenarios. The satin chrome finish reduces glare under shop lighting. The included Declaration of Conformity and Measuring Report support documentation requirements in quality management systems.

Compatibility

Designed for internal bore and diameter measurement applications in the 0.7000 to 0.8000 inch range. Compatible with standard inside micrometer extension rods; maximum extension rod length is 15.0000 inches. No extension rods or setting rings are included with this unit.

Installation Notes

This instrument is used by machinists, metrologists, and quality technicians and does not require installation in the conventional sense. Before use, verify calibration against a known standard and confirm the measuring faces are clean and free of debris. Handle the instrument with care to avoid dropping, which can affect calibration. Store in a protective case away from temperature extremes and humidity when not in use.
