Hi-precision micrometer

The hi-precision micrometer permits direct readings in ten-thousandths of an inch (.0001″) without a vernier, plus automatic control of spindle pressure.
This micrometer features a black graduated inner thimble and sleeve reading in thousandths and a red graduated outer thimble and sleeve with large, widely spaced graduations which give direct readings in ten-thousandths.
It also features an exclusive constant pressure mechanism which eliminates “feel” and automatically insures consistent spindle pressure for every measurement. Extremely to use.
